Review on ASPL 8Pcs Sync Feature Ultra Slim 12-LED Surface Mount Flashing Strobe Lights For Truck Car Vehicle LED Mini Grille Light Head Emergency Beacon Hazard Warning Lights (Red/White) by Kody Bradley

I used this for a motorcycle license plate to bring extra attention to when I was applying the brakes I said it to do three quick pulses then a break and three quick pulses. It is programmable so it brings plenty of attention that I am applying the brakes.Exactly what I wanted. Where the wire comes out of the back Has a small dome of sealant that makes it waterproof right where the wire exits the light about a quarter of a marble sticking out is a good description very small I just used a medium size drill bit to add a divot behind where the light rests and to run the wires through.
