Re: Scrambler 90 headlight kit?
I used a Moose Backup Light for a full-size ATV. It has a 35W halogen bulb and I bolted the included bracket to the front of the handlebar clamp cover. The electrical output of the Scrambler 90 is limited, so you will quickly drain the battery with the headlight on if the RPMs aren't kept fairly high. I also connected power to the existing rear light so it works as a tail light in addition to a brake light.
