Order the smallest, most powerful lights on the market and now will run on 6 and 12V!!! The lights are right at 3.75” diameter. These are machined right here in USA with cast vintage style lenses. The lights are more than 2500 lumen LED lights inside a custom made housing with the vintage style lens that we cast in house. These new lights feature a swivel for easy angle adjustment and a one wire hookup to our cloth braided wire coming from light. The wire can either be ran through the base or out the hinge point, whichever suites your bike best. These lights can be wired up for positive or negative ground so just select that at checkout. 99% of bikes out there are negative ground. The lights are fully polished to a mirror finished aluminum. Orders will ship within one week if assembly is needed. Sold each light. Non DOT approved.
