I feel under powered while reading this thread. I use a 44 lum bar mounted front light. Also a tactical flashlight with 98 lum on the helmet. Today I rode passed a huge truck with it I don't think enjoyed that very much but he was on the bike lane so I don't know what he/she expects. Anyways in the rear I've converted a front 50 lum light to a helmet mounted rear blinking light. That's it I've long thought about the vis 360 as a very best to future upgrade not because I feel un safe with those lights.
