I am considering replacing the stock H/L on my 650L with an aftermarket unit to remove weight. I have already performed all the other weight reduction ideas on the Baja Designs web site and some others of my own. I have been pleased with the Acerbis tail light performance, but am a little skeptical of the performance of a light weight unit. I still occasionally ride at night on the road so I am a little hesitant to count on a "light weight" replacement. :thinking:Any one out there have any experience with the 55/60W unit. I am concerned about brightness, adjustability, durability, and does it vibrate around any. I,m not asking for much huh?
