Customer Reviews
What Drivers Are Saying
Fantastic little flasher! I actually purchased two of these, One for the rear light bar and the other for the corner strobes so I could activate them independently of one another.
I tried two other brands before ordering this one, it was a little more expensive. The first two failed almost immediately. This one is working great. Easy to hook up and easy to select the flash patterns.
This thing is GREAT! If you're looking for a simple "side/side" flasher module, you can't beat this. VERY small and so easy to install. It has a pair of wires going IN (from the power source) and two pairs of wires going OUT (to the lighting source).
