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

I actually wrote a very long review only to have Revain’s App crash. I’ll try to recoup some of what I said.We used these for a lawn mower and a vehicle. Installation was simple. The sync wire definitely made it look professional and eased my OCD. The cabling itself seems thickly sheathed; cable gauge seems appropriate and isn’t just a few strands of wire.Water resistance seems better than many other products I looked up. I don’t believe the lawn equipment has been out in the elements much, the vehicle has received some rain and water and hasn’t had a failure yet.They are very bright. I was able to see them from two streets away through bushes while coming to the facility. I tested them using a 10v, 500mah DC power supply and they were bright enough to not want to look directly at them. I’ll suggest they use a decent amount of current depending on the setup. When using them on the same cable as another set of lights they did dim a bit for 3 of the 4 flashes. Adjusting the pattern on the other lights seemed to resolve that.I’d say they’re good for their purpose. They flash. They’re bright. I’d expect for lawn equipment or construction vehicles they’ll be suitable. I could see some lower funded law enforcement agencies using emergency colors but then again I’m not sure how bright those are. Visibility angle would still need to be checked as they’re somewhat directional; seemingly no less than bigger named manufacturers.
