Review on Partsam 4x2 LED Side Marker Lights: Waterproof Truck Trailer 🚦 Clearance Lamps - Sealed Lorry Caravan Indicators (5 Amber + 5 Red) by Andrew Spainhour

These trailer lights are advertised as being waterproof. I installed it on my boat trailer for an upcoming fishing trip in Texas. These flashlights are not waterproof. When the boat was first launched, the three marker lights on the back of the trailer that had been submerged to launch the boat were filled with water. Then when I plugged the lights back in at the end of a day's fishing, the same lights had more than half the LEDs not working or the lights going out altogether. Overall they are easy to install but now I have to repeat the job with a different brand of lamp and hope they work as advertised.
