OK, this has content for Advocacy & Safety, Electronics and bents, so not sure where to post it. Thought I'd give it a shout here first.
Every now and then I see this guy on a low rider bent with a very bright battery powered light attached in the front, below the fairing. It seems the light is just barely above the road surface. He keeps the light on even during daytime. On earlier occasions I've just thought, "cool, he has a magicshine or something similar, making sure he's visible, good for him".
The other night we met again, it was dark and raining and we were riding towards each other on a grade separated bike lane. His light is apparently pointed nearly straight forward (low mounting point). Flashlight type conical beam, retina searing amount of lumens going everywhere except on the road surface, no cut-off. Looking at his general direction, I couldn't see anything past the light and halo. I could tell he was stopped at the intersection I was approaching, but I couldn't see why. I couldn't tell if he was signalling a turn himself or maybe anticipating a turning car to hook him or what.
Turns out he probably just reacted late to the green light. But had there been any hassle going on in the intersection, I wouldn't have been able to see it. This is the first time I actually felt there's some truth in people complaining about too bright bike lights, and in this case I think part of the blame lies in the low mounting point of the light.
So, what kind of lights do you use and where do they attach in your 'bents? Is it difficult to get a good illumination of the road surface?
