DIY LED BIKE LIGHT... can it be as good as a high end light!? / How to make a bright LED bike light!

Have a look on how I took a $15.00 Mini LED light bar and made awesome Mountain Bike Light that can rival premium bike lights! No joke, the results amazed me!

All in I have $40.00 into this light system. You to can make this!

I love how far we’ve come with LED tech, superior, efficient, and bright. I’ll be using an Imalent Flashlight for my bike lights.

I installed a 9” terra bar 30w bar light on my ebike & it’s brighter than most cars I keep it on high beam until they lowered theirs if not oh well a blinded eye for a blinded eye 😏 & I can tell the difference between factory & aftermarket lights 90+% of the time.

wow i did exact same thing today with princess auto light, and now i see someone else has done it! genius minds think alike haha

[Buck]

WoW, who wouldn't want to take on that project. Thanks for posting.

thanks for sharing the video! you made me realize i actually HAVE this ligh in the flood only beam pattern and it works GREATt!

I designed a mount for mine to be 3d printed. i'll post it here if anyone is interested.

Note the light works from 12v - 30v according to your packaging. so you can go with higher voltage if it makes your system more simple. Actually the light will function down to about 7 or 8v, the light intensity dims down and the light draws much less power as you drop below around 10v. This SHOULDN'T harm the light and it should give you TONS of extra run time.

unfortunately the version of the light i have is Flood only. It still works great as a bicycle headlight, however much of the energy goes up into the sky, and i don't need to see up there so that's wasted energy. And i think i would prefer further light penetration vs lighting up the trees 30 feet above me. I'm going to look for the spot/ flood combo like you have. currently at harbor freight it's listed at $27 for either the flood only or the flood/ spot combo which is a decent price but not close to the $15 you found it for.

I am so glad you did this. I was thinking of doing the same with my old black and decker battery. Look forward to seeing the drawing.

I bought this after seeing this video what a great light for night riding been going out at night since i got it shredding them muddy trails, i add longer wire then connected it straight up to the 2 pin sm plug on my sw900 e bike display

[factionfx]

Glad I googled this...I definitely did not think of the 12v milwaulkee battery I already have!!!

[TravisWilson-hbnq]

Great video man ! Well thought out and totally cool to be doing something like night riding with your son. Keep up the good work man

[johnbobbitt]

light is also sold at walmart. Ive made floundering lights, boat lights, bike lights, even a headlamp from those. for batteries I use the 18650s from either tool batteries or laptops

[bobsoft]

Sweet! Thanks for the link, they are on sale. Time to head out to Langley. I am going to do this setup for my kids electric scooter.

I used what *looks* like the same light bar for the same application on my ebike. The lamp however, on the webpage was rated 12 to 24VDC (Two for $20). When I initially tested them, they both worked at virtually full brightness at 10VDC, so I used a 4s1p Li-ion battery pack configuration (16.8VDC fully charged, down to 11.0VDC fully discharged) and it worked fine. A wide margin on voltages it can use makes battery setup decisions very easy. For other readers I recommend finding a light bar with a voltage range under which it can operate...which gives the user more options on battery pack configurations.
I also used 21700 Li-ion cells at a REAL 5, 000mAh capacity instead of 18650 cells which sellers often over-rate by claiming ridiculous capacities like 5, 000mAh, 8, 000mAh or even 10, 000mAh.
A high quality 18650 at a decent price with a decent number of recharge cycles, isn't capable of providing more than about 3500mAh. Any seller claiming more than 3500mAh for an 18650 is really _"stretching"_ things. The main problem with using 21700's is finding an off-the-shelf watertight battery case for 4x 21700 cells can take some searching, whereas there are lots of such cases on retail websites for 4x 18650 cells.

Thank you so much for this review now we can make good use of our extra m12 batteries!

[electricalmovement]

This was awesome!! Thank you. I have so many Milwaukee 5.0 batteries and can create an amazing led headlight. Great video!

[EiLSeL_OcetOs]

Here in manila. That 6led bars only cost $1.50 i installed that on my ebike😁

[bobthebuilder]

I use 3 led square spot light's on my bike 1300 lumens for the side one's and 2150 for the centre one works perfectly and light's up the dark roads amazingly

[mmmasterscross]

Awesome idea ! Thanks for sharing this video build for the bike light !

[robbig]

Awesome, this is going to help me with my next project!! Thank you!

[steveblanchard]

Great, I really enjoyed watching that and those lights are amazing.
