Review on KaiDengZhe 4X4 LED 4 In 1 Surface Mount Grill Light DC12V Wireless Remote Emergency Flashing Beacon Lamp Police Light Strobe Warning External Light For Truck Trailer Caravan Van (White Amber) by Jerry Mills

The biggest issue was the remote not working with the controller. The lights started flashing when connected to power but despite the light flashing on the remote when I pressed buttons the lights did not respond. I couldn't change the pattern or even make them stop flashing.I highly doubt the IP rating they claim on these as there is no gasket, O ring, or seal on the lights or the controller box. The lights are just a plastic lens and plastic housing over the circuit board with the LEDs and they're not even a good fit because the parts are warped. As for the "aluminum" heat sink they mention and show a picture of, it's just black plastic. I knew these would be pretty cheaply made for the price but I figured they'd at least be good enough I could silicone them and use them until I could get a nicer set of lights installed on my new truck, but they were a waste of time and money
