When I installed my Hotbodies undertail, I noticed a small problem. the undertail did not have provisions for a liscense plate light. This of course is illegal in pretty much ever state in the country, so I had to come up with a solution. THats when I found these. The perfect solution to my problem. they are small and barely distinguishable from standard allan head bolts, the finish is very nice and they are simple to install. just a positive and a negative wire to hook up on each bolt and you are good to go.
