This duo gives you a choice based on your preference. Both choices enhance safety and visibility by bringing Amber and Chrome to the Vertical Air Intake. The 52-823 is an Amber Reflector set into a stylish contoured chrome accent to fit over the non functional Vertical Air Intake. The 52-824 goes one step further by incorporating a pair of 12 LED lights. This greatly enhances visibility and safety and can be wired as dual function running and turn signals for the ultimate improvement to visibility. Both are for the GL1800 Goldwing 2012- 2013, excluding the F6B models.
