I ordered a got a new taillight yesterday and it only has a red & black wire, so I'm assuming its a single filament, which means its a brake light only, right?
is there a way to put a dual filament fixture in there so it would work as a running light also? I'd really like to use this style on my bike
:edit: sorry for being 'that guy'. I just took it apart to check and I was wrong, it will work. I guess it just grounds to the metal of the fender. sweet!
