I'd like a 1,000 lumen+ helmet light with high/low light power.
A built in battery for an approx 2-3 hr bike ride on max.
The back of the light would have a connector that would allow charging through and more importingly an additional battery could be plugged into it that would just have a long lead from you're camelback.
Oh, also maybe a couple of small or one red led on the back of the light.
Very much like the one trout was going to build before the bastid light came out?? :D
800-1000 floody lumens on the bars, 5-600 spotty lumens on the lid, but nice and light if the battery pack is mounted on to the helmet!
Be nice to have 1 charger for all, and atleast 3 hour runtime for both lights, with high/medium/low settings!
