Our "Burst-O-Matic" Taillights are hand machined out of solid 6061 Aluminum, and polished. They feature a very bright 1" round LED cluster with 2 stage, 3 wire, running/brake light function. Sleek, simple and reliable. Designed to mount to 1/4" thick material by one 1/2" hole. 1/2' stainless mounting bolt is included and bored through the center to allow the wires to come out through the back. They can be mounted to thinner material if you add more washers, or trim the bolt to not interfere with the LED cluster on the inside.
