Best Side Marker Light Assemblies of 2026

"I found these lights super bright and incredibly easy to install. After drilling holes in my valance, they fit perfectly—just be careful not to make the holes too large. The only minor issue I had was that the wires are quite thin and a bit fiddly, but overall, it's a solid product."

"For my trailer, these lights are the perfect alternative to standard 3-bar setups. Installation just required drilling three holes, and replacing a single light is a breeze if one ever gets damaged. They're amazingly bright and discreet, and I even connected the brake function for dual use as clearance and brake lights."

"After using these for over six years on multiple trucks, I can say they're an excellent value and really hold up in harsh climates. The installation is straightforward, and the included wire length is generous for a truck bed. If you plan to add more accessories later, it's smart to do the wiring at the same time. Overall, very satisfied with the quality and performance."

"I picked these up to replace old bed strip lights and love the versatility of the pods—they tuck away easily. The light output is just right and less harsh than strips. The only thing to watch for: the wires are pretty thin, and it's not obvious which is power or ground, so double-check before wiring. For the price, though, they’re definitely worth it!"

"I found these lights to be very easy to install, and the included wires were sturdy and long enough for my needs.

"I put these on my gooseneck to replace the old halogen lights. They're very bright and don’t collect water. At first, I thought they didn’t work, but after reversing the plug, everything lit up—so the lights are ground sensitive. I’ll definitely be getting more for my other trailers."

"I switched to these SEALIGHT bulbs on my 08 RAV4, and they’re extremely bright and provide clear, white light, even in bad weather.

"After installing these LEDs in my Honda Element, I immediately noticed a huge difference in brightness—even the low beams are much brighter than my old halogens. They draw less power, were easy to install, and I just added a bit of tape to seal the connections. Great value, highly recommended if you want better visibility."

"I recently installed these for a client who struggled with dim halogen headlights. I was impressed by the sharp beam pattern and crisp white light—no glare for oncoming traffic.
