I'm geek and I'm proud. Face my taillight and feel the burn!
FWIW, if it wouldn't take a larger battery than I care to tote, I WOULD use a car headlight. Not really. I don't actually use my powerful lights to light the road far ahead. You would probably be surprised at how close it is pointed, BUT I can see every detail in that area plus pretty far ahead and far out to the sides.
Besides, it's not about the light.
