Bright Bicycle Lights – A Public Service Announcement

Bright Bicycle Lights – A Public Service Announcement

Make sure your lights are angled down and don’t use too bright a setting when it’s dark and there are other road users on the road. You will blind / dazzle them which can lead to accidents.

I’ve used all sorts of lights, ranging from crappy cateye lights right up to fully off-road 1600 lumen lights. All of which are quite easily usable on the road, that is if used on the correct power and dipped to the right angle.

    Thankyou so much for putting this up here.. Bright lights are dangerous, bluer lights even more so, and flashing lights a fucking nightmare- please please please stop the flashing and angle the light down, are you blind?

  3. john argue on August 15, 2022 at 12:58 am

    There certain lights sold with a cut off point . Super bright but cuts off at certain height.

  4. dummkompf on August 15, 2022 at 12:59 am

    ehhh… this is just how it looks on the camera, which can be very different from real life. even if it looks like this to drivers, at least there’s no doubt they will notice you!

  5. KING OWO on August 15, 2022 at 1:00 am

    Stupid video. Pointing lights directly forward is the safest way to go.

  6. Dave Cunningham on August 15, 2022 at 1:01 am

    Very informative video mate. Thx for uploading

  7. Tactical Ninja on August 15, 2022 at 1:01 am

    I have a dual power light so it does both high and low beam and so far it is perfect. I also have a few underpowerd flashing led lights attatched to my bike so basically iv grabbed attention, can see great without blinding anybody, but can go high beam in the forest or if i choose to actually blind people 🙂 its perfect for night riding anywhere i like

  8. Alex Braun on August 15, 2022 at 1:03 am

    I think that most of those super bright cree lights should be banned on public roads and certainly not allowed on flicker mode…thay could send a stone into an epileptic fit. They are too bright, they blind you and in fact do not help the cyclists…try luminosity rather than brightness…

  9. Adrian Brown on August 15, 2022 at 1:03 am

    This light helps to get you recognised from both front and back

  10. Plumberman Jones on August 15, 2022 at 1:04 am

    As with everything else, it’s not what tools you got – it’s how you use them.
    A lot of "road users" adjust the settings of their lights wrongly. I’ve done it.
    There is no point lighting up the whole road if you blind someone and they crash into you.

    Lets ALL respect each other.

  11. Arioch on August 15, 2022 at 1:04 am

    The over power is slightly aimed higher then the other one and that is done on purpose cause those morrons want to see farther down the road, they careless about blinding the rest of the people on the road. If police get enough calls, theyll start cracking down on it just as they do when getting complaints about speeder, drivers not stopping for pedestrians at crosswalks, texting while driving. They go and look out for those violators. I have 3 high beams set up so I turn on and leave it on if after flashing they leave high beams on, other than that, I flash real quick and point out by pointing then close open hands real quick hoping they undertand when their next behind me or when they pull up, I yell out nicely so they wont shut down and not listen up.

  12. David Banfield on August 15, 2022 at 1:05 am

    And if you said "kiss my ass to the police officer then you deserve what got "

  13. David De León on August 15, 2022 at 1:06 am

    you got the point, the angle, not the brightness

  14. Tim Lewis on August 15, 2022 at 1:06 am

    I just bought a 4000 lumen that can illuminate a room more than main lighting. It also has a full brightness disco strobe! I’ll have to angle it down. I have rainbow coloured spoke lights for side visibility.

  15. trynodev on August 15, 2022 at 1:07 am

    LED improvements are allowing portable lights to become very bright these days. Unlike stock headlights on cars that point down and should be adjusted if not, the uses of these very bright lights seem to be very naive to the issue. I use a Cateye light with 300 lumens and it seems to be plenty bright. I often dim the light when I don’t need the full power. These bright lights are made for back country cycling at night, not for roadways. To increase visibility, you are better to buy two lights of 300 lumens or less and use them together, or use them together at their not so brightest setting after dusk.

  16. David Banfield on August 15, 2022 at 1:07 am

    Thanks for this. I am a bus driver and although I can see a cyclist using these light from about 200 yards away you get a very distorted idea of their ACTUAL distance due to the dazzle. I also with Whitney that I have to look away to avoid damaging my eyes. It should be remembered that a bright light shined directly into your eyes will cause the iris to close which is undesirable at night because you will be able to see less well, this defeats the object of using overly bright lights in the first place. I think a better solution would be to use a standardised and  regulated brightness of lights fitted to bikes – yes, just like cars – and then have white reflective strips on the front of the bike and red on the rear. I know you guys hate the thought of cyclists being government regulated and feel it offends your freedom but motorists have had to accept and swallow every new law and regulation over the years whereas cyclists have largely been ignored. A real change needs to occur and it will only happen when the cycling community WANT it to change. Please do not take offence at any of my comments, I am trying to be constructive. By the way, I am VERY considerate to cyclists, never tussled with one and never knowingly hindered one (even the ones who ride like twats!)

    I’m being followed by …. the sun!

  18. Stu Wright on August 15, 2022 at 1:09 am

    had some idiots dazzling me with their cycle lights on the way home through park tonight , told the first one that its TOO bright, bloody idiots.

  19. john smith on August 15, 2022 at 1:10 am

    As we get more cyclists they should be more regulation and enforcement – simply blaming drivers for discourtesy isn’t right; that argument cuts both ways – both cars and bikes seem involved in a passive aggressive lighting arms race

  20. Jacob's Handyman Tree Service LLC on August 15, 2022 at 1:11 am

    Is that a ghost or angel following him from 2:40 to 3:30?!?!?!? xD

  21. HookahGuy Ty on August 15, 2022 at 1:18 am

    No different than the car head light next to him or a motorcycle head light. You see the light means a vehicle or object is there. It’s behind you? I could understand somewhat with trucks with HID blinding you while driving I do think angle it down however can’t stop all the light .

  22. Peter Renton on August 15, 2022 at 1:19 am

    The thing is, in the city, these lights are for the benefit of the vehicles on the road, the streetlights are generally good enough to see by, so you need to point your lights at driver level so they see you.I’ve just started rocking 15k Lumen lights on my handlebars and I leave a 5k one on my helmet.  You have to put your own safety ahead of drivers who generally aren’t on the lookout for cyclists.

  23. Vancouver Camera Cyclist on August 15, 2022 at 1:20 am

    He needs some side lighting like the one on my bike. Once beyond a certain angle, his light disappeared. I aim the yellow straight and the white slightly down. Yellow doesn’t bleach our rod cells as much as white so it should be safer.

  24. John Bull on August 15, 2022 at 1:23 am

    Reassuring. I sometimes wonder whether my light isn’t blinding, but I need it on dark country roads. But the one in this video is significantly brighter than the car headlights, and mine isn’t. Plus it’s a question of the angle being too high. About time someone made bike lights with dip and high settings really.

  25. Gillenz Fluff on August 15, 2022 at 1:26 am

    Looks like a good way to almost stay anonymous in rear facing cameras!

  26. David Banfield on August 15, 2022 at 1:27 am

    Just wanted to add another relevant point. reflective clothing is much more effective than hi-viz clothing at night which is almost not worth having. White is actually more effective.

  27. Christopher Staples on August 15, 2022 at 1:27 am

    OMG someone tilt that light down

  28. Andrew Howden on August 15, 2022 at 1:28 am

    I think it reflex his ego he insis on being the britest and the fastest.

  29. Matt Baigent on August 15, 2022 at 1:28 am

    I’d rather have an overly bright light than a dim one. I totally get where you are coming from but take myself for example, majority of my riding is done off road at either 5:30am or 7:00pm so I would need a bright light so I got a niterider pro 1800 but some of the time I ride on roads and I am not going to fork out an extra £190 on some lights just for the road. My light is designed for flood lighting and no matter how far down I angle it, I am still likely to dazzle on coming traffic

  30. George Prime on August 15, 2022 at 1:29 am

    What an absolutely selfish pillock.

  31. GravelTramp on August 15, 2022 at 1:31 am

    My rear light kicks out about 400 lms, great for a daytime runner. I do generally turn it down at night due to it dazzling drivers, really slows them down though when approaching, even on about 100 lms. My front pair kick out around a genuine 3000 lms. Usually I only use one on low power at night on the main road, and still have to angle it down. It does get cranked up on unlit pot holed lanes. And off road I will let hell lose with 3000 lms. Bright lights are safe when angled correctly. More importantly is clothing, day glow and lots of scotchlite at night! It really bugs me how lots of riders appear to like to camouflage themselves in blacks, blues etc, usually roadies too! Thick or just plain stupid, I’m not sure? Some cyclists really have very poor hazard and personal safety awareness, they really don’t appreciate how vulnerable they are are! It’s bad enough on a motorbike!

  32. pirko101 on August 15, 2022 at 1:32 am

    In town where this video is taken, can you as driver of car go faster than 25 kph because all I can see is bunch cyclist go zig-zag in traffic?

  33. Edward straka on August 15, 2022 at 1:34 am

    that bright light is over powered for city riding. it’s washing out an depth perception.
    it would be fine for off road riding. if you do feel the need then use the beam intensity setting, just like you would in a car.

  34. Angela Cammish on August 15, 2022 at 1:34 am

    did or have you spoken to him?,those lights aren’t cheap I think its an ego thing myself.the best light for low light urban riding is flashing I think and most lights flash. many videos say 200 lumens is enough tops, and yes it wud ennyoy car drivers as well 🙂

  35. Sky Driver on August 15, 2022 at 1:34 am

    Unless you ride with your eye-level at half a meter off the ground, I don’t see the issue.

  36. David Banfield on August 15, 2022 at 1:34 am

    John F, in my humble opinion yes, that would solve the problem. Maybe it simply requires someone holding your bike upright while you stand about 50 metres away. Then just use common sense to judge for yourself. All of my comments are just my opinions so I hope they help

  37. motorbiking on August 15, 2022 at 1:34 am

    Its not about the lumens – its about where they are pointing.  I use torches for my front lights: two attached to the bars which will run happily at 800+ Lumen each (Cree XM-L2 LEDs at 2A), though I normally run them at about 1A.  I get no problem with people being dazzled because I angle them down and slightly to the left.  There used to be a fashion among motorcyclists to filter traffic on main beam in the hope that the light was picked up in the mirrors.  Unfortunately a dazzling light reduces a persons ability to judge speed and distance, so its the last thing you want.

  38. carreteras101 on August 15, 2022 at 1:39 am

    thank you for making this video. think of it this way; there are laws for headlight brightness and aim on motor-vehicles for a reason. bicyclist with blinding lights are annoying and dangerous to others.

  39. Dex Lei on August 15, 2022 at 1:40 am

    Its not even dark… why do they even need lights?

  40. Iow3freq music 🏴󠁧󠁢󠁷󠁬󠁳󠁿 on August 15, 2022 at 1:40 am

    Why can’t the UK government (what’s left of it at the moment) bring in regulation for dipped beam bicycle lights like in Germany with their StvZo approved lights.

    We need more companies investing in proper reflector designs so we can have high power lights that do not glare like proper car headlights.

    There are only two real proper options at the moment (2018/2019) I can find, Lupine (Germany) SL models, Exposure (UK) Optix All Terrain StvZo model (new product N/A via website) both are very expensive around £300-£400 quid each. These range from 900 to even a few thousand lumens in the Optix apparently. There’s also a flashlight company Fenix that has a few models of bike lights with dipped beam features and Ravemen has some good lights but there is not much choice for cut off beam type lights at least that I can find, most for sale (like on cheap Chinese sites) are just blinding mtb lights that throw a circular beam, great for the mountains but not for busy roads. This is coming from a non-driver by the way.

  41. Dr Who on August 15, 2022 at 1:40 am

    The cyclist with that EXTREMELY!!! BRIGHT light hasn’t got the jist of setting the front light at a SENSIBLE!!! angle as not BLINDING to other traffic. NOR was there any reason for it to be on FULL!!! If I had been there & had that in my face ( so to speak) I would have said something about it to the rider.

  42. Angela Cammish on August 15, 2022 at 1:46 am

  43. Forename Surname on August 15, 2022 at 1:47 am

    These overly bright/misaligned bicycle lights are just as bad as who chavs fit £20 hid kits to their shitty superminis without projector lenses. Completely blinds you on country/unlit roads, it’s common courtesy for motorists to turn off their high beams for other road users. Yet some cyclists think it’s fine to ride around with blinding lights all the time.  If you have to cycle on a unlit road (where you require high beam/unaligned lights) use a separate light to what you use in the city. It’s a shame we get cyclists who demand equality yet don’t give a shit about other road users.

    There’s a firm line between being seen and being a wanker!

  44. Donald Malone on August 15, 2022 at 1:48 am

    I love getting blinded by the high intensity lights on vehicles now-a-days, So much fun to swerve away from them and stop to get your eye sight back. So now I resort to their fine equipment. Two rectangular off road halogen lights for trucks, The lumens,, Have no idea, But have no problem bringin the sun out at 10 pm. 12 volts- 55 watts and I push 18 volts to them via Dewalt rechargables.

  45. WalamusPrime on August 15, 2022 at 1:49 am

    It’s hard to prove a point about light brightness though YouTube since whatever camera you use to record the video is going to have its own sensitivity/exposure levels which is going to be completely different to the sensitivities of your retinas.

  46. Clinton Leonard on August 15, 2022 at 1:50 am

    I have two front lights. A headlight, and a lower powered light that has multiple settings and can be seen from 180 degrees. I use the 180 degree light for people to see me, and the headlight for me to see. The first light I usually set to blinking mode since it saves battery more than continuous light, but my headlight i keep angled to the road at low, solid light setting. But even that low setting is damn bright; it helps me spot potholes and such at night.

  47. John F on August 15, 2022 at 1:50 am

    so if he just angled it down, would that bright of a light be ok?

  48. 1love 1heart on August 15, 2022 at 1:50 am

    got to love the cree power .

  49. giacotubo on August 15, 2022 at 1:51 am

    very interesting video; probably lack of standard norms about this matter cause what you described very well.
