I may get flamed for saying this, but using lights especially the front light is a seasonal thing for me. I never run lights on my bikes full time. I usually remove my lights some time after winter when the days are getting longer during spring time and I don't put them back on until fall. I only use lights when I feel it's absolutely necessary. All my lights are cheap, I use PB superflash rear blinkys and for the front I have some cheap BLT lights...The only expensive lights that I have is my front helmet light which I use during winter time and I never leave my helmet on the bike when locking outside.
