    Installed on my 07 Street Glide, works great. The added light from the blinkers make the back end much more visible while braking. Easy plug n play install.

    Makes Turn signals into Car third brake light

    Posted by Brian F on 24th Jun 2013

    Nothing catches peoples attention more than a completely dark light that comes on when you brake. This unit makes your turn signals function like a car's third brake light. I believe, because of this that this unit is better than the run and stop tailbones unit. Just my opinion! Couldn't be happier! 2003 Ultra Classic.
