Rising like a Mako shark on the back of a motorcycle fender, our first taillight looks like the dorsal fin on the ocean predator of the same name The Biltwell Inc. Mako taillight is for custom applications only, and will not retrofit to any stock motorcycle without several hours of easy drilling, wiring and soldering If you can change a light bulb, you can ditch the giant taillight on your stock hog to make room for this tidy little taillight This taillight is constructed of Investment-cast aluminum, extra thick injection-molded polycarbonate plastic lens with 5-40 Phillips head mounting screws, a die-cut rubber base gasket and internal LED spacer gasket, custom 15-element LED board with two phases (brake light and running light) and three wires (ground, brake and running lights); 1/4-20 hex bolts for mounting through the underside of rear fender
