Having seen those multi LED auto lights in operation, they're pretty weak. Actually, they're very weak...even for a bike.

But, there's some good news in automotive LED lighting. The new Prius uses LED bulbs in it's projectors, I'm sure other cars will follow eventually. It may eventually replace HID projectors.



Dedicated hybrid or electric cars like the Prius or the Volt often utilize the most energy efficient headlights available. The Volt uses HIDs, for example, which are much more efficient than halogens as did the Prius up until it's latest inception.

Unfortunately I don't know the Prius bulb's current draw. But if you want a 12V LED automotive lighting system, this would be it. I've custom built HID projector headlamps for several of my cars and others before, harvesting the projector from a Prius headlamp and mounting it to a bike probably wouldn't be any huge deal. Expensive though, likely.

But again though, being somewhat of an automotive lighting aficionado...stay far away from the cheap aftermarket lights. Especially the ones with 50 billion LED's plastered all over them. You could get the same amount of light from a $10 flashlight for a whole lot less money and weight.

BTW: LED driving lights aren't that new. I bought a set to try out from Advance Auto Parts four years ago I think. They were awful.
