Could you post a highly detailed instruction and shopping list? And maybe instructions for building something with less than 7000?

I can build stuff, but I don't understand where to start with the electrical.

I would also like more info on this, especially the power pack and the building of the light/heatsink.


Yeah i can work on a detailed instrustions and a parts list as soon as im done with finals for this quarter. I got most of the parts from ebay with few things I had layign around. If you want a smaller light it becomes much easier. I built a 2000 and 3000 lumen for my road. I give instructions for that unless anyone wants help building a bigger one


I'd love a write up for how to make the rear lights, I've always wanted something like that for my road bike. I don't trust drivers.


That is a great light!

Riding in the city I still feel like I need a very bright light, and often wish my bright $$$ LED lights were even brighter. In fact, I think I'm going to try to build a helmet light next winter to complement my handlebar light. Deep craters and road seams sneak up on riders and before they know it, they're flying over their handlebars at 20mph. Furthermore, motorists here have a lot of bright visual clutter to deal with at night, and I think a very bright light helps approaching and oncoming drivers recognize me as a moving vehicle during their saccades, and not something static and in the background.

Thanks for posting the pony bike earlier this month. :)
