I've been having a blast on my new CM200, but I've noticed a serious deficiency in headlight brightness/spread. I plan on using the bike to go camping soon and Im trying to figure out the best way to brighten things up. I cant find any "off road" lights that run off a 6v battery and I think I figured out that the headlight is a sealed beam so I cant replace the bulb, i have to replace the whole thing, but I cant find the info/size! Please help me figure this out. Thanks!
