Item:    SD01009    Signal Dynamics

This is a Back-OFF wig wag brake light flasher. This module is designed for use with motorcycles equipped with two brake lights located side-by-side. Do not install on a car or truck's brake light or turn signal system. You can choose between two different modes when installing. Mode One: Emits 4 alternating quick flashes of the left and right brake lights, followed by 3 short flashes and 1 long flash (3.5 seconds) of both brakes lights. The 3 short flashes and 1 long flash pattern automatically repeats itself as long as the brakes are held. Mode Two: Emits a visual signal of 4 alternating quick flashes of the left and right brake lights, followed by 3 short flashes of both brake lights and then the brake light remains steady until the brake is released. This is great for increasing visibility! This comes with instructions and will fit all years of Goldwing 1800's from 2001-2010 as well as all Goldwing 1500's from 1988-2000 and Goldwing 1200's from 1984-1987.
