Upgrading the lights on your trailer, truck, RV, or boat? This 2-pack of oval LED lights from WahMOTOTin is a smart move. Each light is 6 inches long and has a super cool halo design. Here's how it works: The outer red halo ring acts as your running light (low brightness), brake light, and turn signal (high brightness). The inner white LEDs light up bright when you put the vehicle in reverse. That's two functions in one sleek light! They're surface mount, meaning you just need a small hole to run the wires through and then bolt the flange down. Wiring is simple with the included 4-wire pigtail harness (white=ground, yellow=reverse, red=brake/turn, black=running lights). They're built tough with an IP67 waterproof rating, so rain, snow, or mud won't bother them. They use bright, long-lasting LEDs that are much better than old incandescent bulbs. They're DOT/SAE compliant for road use. Perfect for utility trailers, enclosed trailers, flatbeds, dump trucks, vans, you name it. Improve your visibility and safety on the road with these modern, reliable lights. The pack of two has you covered for both sides of your vehicle.
