Now that you are running that CDI setup, and your spark is great, lets work on your lights!
This is conversion beam setup that fits right into your standard CEV bucket, works on many mopeds. It allows you to run a super standard and easy to find Halogen H3 bulb that you can pick up at most automotive supply stores or right here. Great for hi-rpm CDI setups, and or mopeds with kits. Stock bikes with 12v systems can run these fine as well.
You probably don't need a voltage regulator, but why risk it? This bucket will go on pretty much anything you want to put it on.
This setup comes with a 12v35w bulb but most of the H3 bulbs you'll find at auto supply stores etc. are 12v55w. Have a crazy power lighting coil? 12v100w H3 bulbs are available too!
