TMH (Pack of 20) 20 Pcs 3.8" 6 LED White Side Marker Lights, Trailer Marker Lights, Rear Side Marker Lamp, Led Marker Lights for Trucks, Cab Marker, RV Marker light

work well

Out of the 20, I had one with a dead LED and another that just wouldn't turn on. I only needed 16, but you would expect that all would be fine. They are bright and work well.

Are these bright? Yes. Are they waterproof? No not at all. I purchased two 20 packs and one 10 pack in the last 30 days. 6 lights were DOA out of the packages total no matter how polarity was connected. Into the trash they went because the seller wasnt at all helpful backing the product with a warranty. The lense is where I'll start. Is it glued on? Yes. But not all the way around so water gets in when it rains. Youd have to seal around them with silicone to actually be waterproof. The lights I didnt silicone got water inside and died some in 24 hours. After install. You will see in the pics I uploaded. Also something inside began rusting immediately when moisture got inside. I am not using these on a trailer or vehicle but as stationary accent lights mounted to aluminum angle outside in a 12volt application. Do they look nice once siliconed? Eh not really. Are the led boards mounted to the plastic tabs well inside and level? Nope. The wire on these isn't copper. It is aluminum. It will corrode fast so make sure connectors are water proof. Also the wires are not UV rated. If the wires see sunlight they bleach white in about a week. Yes one week the wires will be snow white minus the 7 dwarfs. Remember these are budget 12 volt lights. Would these work inside a trailer? I think so. Outside? Eh unless it's for a temporary fix dont use them. It's just not worth it. I purchased a 10 pack of orange. How long did those last? 13 days. And yes I used the foam gasket. But water still got inside. Buy with caution.

Nice

Used on boat trailer

These throw a nice light for storage compartments and cupboards. Low profile and draw very little power. Using them on my RV.

these are not the brightest lights by no means, but in my application they are perfect. I used them to light up the back of my truck with a contractor camper shell, with magnetic reed switched to turn them on and off, and when you need light, they provide just enough. nice and thin and look clean. if I need them, I would buy again

Used these lights in truck for interior lights. They worked great for this app.Easy to apply
