I have a metallic blue 2005 1800. I originally wanted a blue spoiler, but the factory no longer makes it. I am not a big fan of lots of chrome do dod not order the chrome spoiler, but this sits under the trunk and definitely is bright and looks nice. There are 2 red plugs and 2 blue plugs under that center piece. I plugged it into the blue plugs (you can use either). Last thing: A Highway Patrolman (who rode a cycle for work) told me years back, when I had a 750 Honda, that having extra lights on the back of a cycle is one of the safest things you can have for protection. Besides adding this - I have a light under the license plate and a running lighted mud flap.
