TMH 20 Pcs 3.8" Amber + Red Light 6LED Side Marker Lights, Trailer Marker Lights, Rear Side Marker Lamp for Truck Trailer RV Boat Bus Lorry LED 12V DC

These are the brightest led lights you would ever want on a trailer. My flatbed illuminates the whole neighborhood when I drive through.

I bought these trailer lights as they were an exact replacement for what was on the trailer. Someone had mostly used rivets to put the original lights on which I noticed but did not think much of. Once I attempted fastening the new lights on, I realized why someone had used rivets. The nut/machine screw combo is no good. I'm a machinist by trade and understand nut/thread tolerances and types of metals commonly used in nuts and bolts. The nut fit on the threads is too loose and unable to tighten up without stripping, almost with finger strength. Cutting to the chase, I ended up going to the local hardware store and purchasing 4-40 stainless phillips head machine screws, washers, lock washers and nuts which solved the problem. The lights are fine and a good price, just plan on tossing out the hardware.Scooter...

Good light output. Decent structure for the price. The body is a little flimsy and the wiring is mediocre. I expect to have some wiring pull out over time due to the lack of sturdiness in their attachement to the light body. However, for the price i am very pleased.These are two wire lights. One for power, one for ground. A lot of trailers only have the the power wire ran to the lights and the light is grounded via a metal connector on the body. This requires you to run a ground wire. Not a huge issue but it definitely is something to be noted if you’re doing a big trailer.

the cost was good they came quickly and are as bright or brighter than the old incandescent lights on my big horse trailer. I got tired of changing lamps. I did notice when I hooked up to the trailer after changing all the running lights tail and license plate lights the draw on my amp meter dropped quite a bit. not sure exactly how much but this is a big 4 horse trailer with a full tac room in front. I would buy again at this point.

Purchased to install on a open car hauler. Once installed these things now show me where the trailer is in the lane. The lights also allow other drivers to know I am towing a trailer and where the trailer is.

Installation is okay but you have to drill three holes for mounting. It would be nice if there was a "channel" in the molded case so you'd have the option of not having to drill the middle (third) hole.

Nice lights, I would like the wires to be a little heavier. These were simple to install and so far, work very well. I used them as clearance lights for my cargo trailer.

Filled with water and shorted out.
