Review on XT AUTO 6LED Car Truck Emergency Beacon Warning Hazard Flash Strobe Light White/White 4-pack: Maximize Safety with Brilliant Flashing Lights by Joe Merculief

Sturdy construction. The screws break easily, so be careful not to over-tighten them. Otherwise I am very satisfied with the price-performance ratio. On the dyno test they appear to be very bright. I'm waiting for a new junction box for final installation on the car but they look great! TO UPDATE! These lanterns are in very good condition. I have 2 inside and 2 on the bumper. I added some silicone on the back of the outside mounted ones for extra weather protection for safety. Very bright. The only downside I've found is that I can't get them to sync with each other.
