OPT7 Sidekick 48" Running Board Lights 2PCS LED Strips w/Amber Turn Signal Side Marker, DRL, White Courtesy Light for Regular Cab Trucks Pickup SUV Trailer

Nice and bright fantastic

Only on a week but so far so good. Look good and nice light.

I installed on my 2019 GMC 3500 Duramax. They look great, offer increase visibility and work as described. I opted to use all my trailer light circuits to power them instead of cutting into the factory wiring harness. Just use an "add a circuit" (available on Amazon) and plug directly into your fuse panel under the hood, if it shorts the system out for whatever reason on the road, it's just the trailer lights affected, not the truck itself. I've had them for 4 months now through a Canadian winter and they still work great! NOTE: Be sure to really clean the surface before you stick them down.

So I’m just an average guy with basic knowledge and master of none of them. It was very challenging installing these due to not having a dependable wiring diagram for my 2021 F250. They vary so much based on year, model, and options. I eventually gave up and did trial and error. Here is what I learned. 1) throw away the blue splice clips, they are garbage and don’t make good connections. Even cost me time because they made me think I was on the wrong wires. I cut my wires, spliced them in by twisting them, capped, taped, and shrink wrapped. (Overkill prob but I didn’t want any issues) 2) buy a cheap multimeter from Walmart or wherever and go on YouTube to learn the absolute basics. If I can, anyone can. It will help a ton if you go the route I did with trial and error. 3) Shrink wrap your connections and a large one over where the wires leave the lights. Will protect from weather. I even bought corrugated tubing to protect the wires until they went into the cab. 4) There are many way you can prob get this done. My way is just what I did. I found a constant power with the vehicle on, a ground (although I was told making your own is better), I pulled my taillights to find the blinkers, and I found a courtesy light wire for the white light upon exit. The lights themselves are absolutely awesome. Bright, match the amber running lights, provide plenty of white light when entering and exiting, and you can’t miss the turn signal. I cleaned the surface with brake cleaner and they have not come loose at all and have been on for couple months now. If you have a wiring diagram the install will be a breeze. If you don’t, be prepared to have some patience. The difficult of the install has nothing to do with the lights. It has to do with every vehicle being different. Not even about different makes, but based on year, model, and options. If that isn’t hard enough, the wiring colors on driver side and passenger side were different. Even with the difficulty, I’d buy them again.

They've been working exceptionally well on my truck for about a month now, handling snow and rain without any issues. Brightness and durability are impressive—I really love them!
