Designed to be used with the ABS Beetle body to fit the optional clear lenses that come with it. The rear has 2 small holes that can be used with some 1mm brass rod for positioning on the fenders. It also has a hole to take a 5mm led. It must be a flat top one, regular domed LEDs are too tall and the clear lens won't fit. You'll also need to enlarge the centre hole on the fender slightly as well.
