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 in Amber by Ryan Hadden

The first thing to know - and it's clear from the description - is that these are just turn signals, no control box or extra wiring. They have about 4 or 5 inches of wires coming out the back and you add what you need. I'm using them to replace some of the running lights (along with the rear turn signal) on a trailer stage that our TV station bought for remote events. The trailer is wide and tends to be very close to traffic on either side of the lane, and in heavy traffic we want to improve the trailer's visibility and alert motorists to keep an eye on it. Installation is easy. We simply used special screws (due to the material of the trailer) and properly installed the turn signals in the supplied waterproof rings. A little caulking of the hole the wires go through - because we're being too careful - and there are no problems. We haven't pulled the trailer yet, but I'll add pictures when we do.
