    Wow those lights are expensive. I have a custom bafang ebike and what I do is get a 30$ headlight from aliexpress(Idk the lumens but it’s brighter than most car headlights), a 60v to 12v regulator and mosfets so I can use the bafang remote as the lightswitch. If not, a simpler solution is to just wire a headlight in parallel with the battery. The downside to this being that if your Ebike is on, so is your headlight, but it’s a lot simpler requiring no soldering. If anyone’s interested I’ll give some documentation on how I did it.

    According to magic shine ,3500lm light will only produce 1800lm on Shimano e8000 output terminal due to the limited voltage 🤔

  3. Zzzyax on April 26, 2023 at 8:25 am

    I got my first EMTB yesterday and thought there must be a way to wire in lights to the system, Yes! Just do this. Mine is SR Tuntour but has the option for lights on the controller just a bit nervous about dismantling like this, if anyone has any videos on that specific system let me know (Carrera Vengeance E)

    As mentioned already, for Bosch motor there is an additional step of activating the light port at your dealership. What’s worse, after activation certain battery capacity will be reserved for the lights, doesn’t matter whether you use them or not. In my case, it was whopping 10% of battery! So instead of having 625 Wh battery you now have ~ 560 Wh 😢
    I ended up deactivating the port and going with the battery-powered lights.

    6:49 That’s what she said! Giggedy 🙂

  7. Tom Prince on April 26, 2023 at 8:42 am

    Hi embn, great video, as if it is that easy. I have a magicshine monteer 3500. Will I be able to run this using the MAGICSHINE® MJ-6290 SHIMANO LIGHT CONNECTION CABLE?

    This would be great to know!

    Cheers guys

  8. Paul Wood on April 26, 2023 at 8:42 am

    I would be interested to know what the per-lumen battery drain is and how running a light on full beam would reduce range.

  9. Phil Barker on April 26, 2023 at 8:43 am

    I run a lezyne 1000 on my emtb, it’s really been fantastic not having to charge it and always having it with me in case a ride runs on too long and I need a light to get home.

    One thing to note if you have a Bosch system, you have to take the bike to a dealer to have the light enabled in the software 🙁

    I made new switch for my ebike. I call it the bling switch. I used relays.. when ever I could used led hindsight.. didn’t need long as led

  11. glenra123 on April 26, 2023 at 8:46 am

    So, it is better to "have a longer length than a shorter one"? 🤔 😂

  12. Rubinstein Kleer on April 26, 2023 at 8:47 am

    I use magicshine on my 2021 Giant trance. There’s a plug in the head tube for the cable so no motor faffing required and there also a light switch already built into the motor control on the handle bars, couldn’t be simpler

  13. AmvC on April 26, 2023 at 8:47 am

    For BOSCH CX 4th gen (maybe others) motors: the light port at the motor needs to be activated by a bike shop which needs to have the bosch service software. No plug and play here – and 5€ gone. It’s just the typical BOSCH move of ripping you off 🙂

  14. Antonio Latorre on April 26, 2023 at 8:55 am

    I’ve been saying this for quite a while. The next ebikes designs would need to bring near the screen or top frame a USB port to easy plug and play a lamp, smartphone, etc. just make sure to put a plug on it to avoid moisture or water coming in and ready.

  15. Sussexperformance on April 26, 2023 at 8:57 am

    Is it that easy to fit to a older steps motor ? E8000

  16. Steve Crump on April 26, 2023 at 8:59 am

    Lights on your e- mountainbike look cool….I especially like the day time flash mode….👋

  17. Thim on April 26, 2023 at 9:00 am

    Curious how much light drains battery? Some of the longer rides I do requires me to turbo in quite a few steep hills and makes me wish I had a larger battery or smaller ones that I can fit in pack.

  18. Dariune on April 26, 2023 at 9:05 am

    can you just wire me an E27 socket on a bracket? I have a $5 osram led bulb that pumps out 2500 lm

  19. Ron Mel on April 26, 2023 at 9:08 am

    It’s funny that this video comes out today as I tried hooking up a LEZYNE 1000 just yesterday with no joy. When going into the bike’s computer, it wouldn’t let me go further into the light menu to choose the on/off option. It just kept double beeping. I have the Shimano ep8 motor with the em800 display. Any help would be appreciated.

  20. One Rider on April 26, 2023 at 9:08 am

    I went with clip-on lights. I never use my wired-in lights, because I ain’t trying to drain my batteries on something that doesn’t make me MOVE…

  21. johnpcwarrior on April 26, 2023 at 9:12 am

    my bezior x1500 came with led light very good for night time. very good explanation on how to do it yourself🙂

  22. Mark H Hendricks on April 26, 2023 at 9:14 am

    What is the wattage and amperage draw of your light?
