Where to mount auxiliary lights

[Gone in 60]

I haven't really noticed any problems like dead zones or shadows. I have them angled out a bit to the sides, but not by much. Since I mostly ride on well-lit highways, like commuting home during the winter months, I don't have the advantage of seeing how well they'd work in a remote area. My best reference is a single-lane carpool overpass that I take that travels for about a mile over a major interchange. It's fairly dark up there, and the Rigids put out a good amount of light down the road and up both concrete barriers to the sides, even in dim mode, which I use at night during city riding so I'm not blinding anyone.

You are right, the wires run up the brake lines and into the headlight bucket for power. I have a small push switch on the lower triple clamp that I can reach down and tap to toggle between bright and dim for day and night riding.
