Review on 🚨 Ultra Slim 4pcs LED Warning Lights with Sync Feature for Car Truck, Emergency Hazard Construction Caution - Surface Mount, Main Control Box Included by Dustin Lannan

These flash lights were super easy to install and amazingly bright! The quality is good and everything works fine after 2 weeks and rough weather. The installation time for me was about 3 hours. To be honest the hardest part was finding the hidden grommet in the firewall to get the wires through! A few notes: the kit was ok but I had to buy another set for my grill. Also, the switch and body aren't backlit, so you'll need to be careful when changing the flash pattern. But it has memory and saves your last settings. After all, everything was already wired and connected to the controller, so make sure you pay attention to which strobe cable goes into which hole in the controller box, otherwise the pattern sequence could get a bit out of joint. Very satisfied!
