Review on 🚦 High-Quality 2pc 2.5" Amber + Red LED Trailer Marker Light: DOT FMVSS 108 Compliant, SAE P2PC Certified, Surface Mount, Waterproof IP67 – Ideal Clearance Side Marker Lights for Trucks & Trailers by Shah Moser

These gauges/lights were a good replacement for the originals on my trailer. Much brighter! I only gave 4 stars as 1 out of 8 bulbs didn't work and the metal screws that came with it are rubbish. You'll have to buy higher quality screws if you want to use them on regular steel. Also note the tabs that snap onto the bezels. As you can see from the photos, I broke the tabs on two of the headlights when removing them with a metal screwdriver. Use a plastic tool. I contacted support and they gave me a credit to buy 3 new markers. As mentioned in other reviews you will probably need to drill new holes as your trailer gets older. My trailer is 15 years old so I spent hours drilling new holes and connecting 8 new bulbs but I am happy with the end result.
