HERCOO Side Mirror Marker Light Turn Signals Lights LED Sequential Switchback White & Dynamic Amber Lamp Smoke Lens Assembly Compatible with Chevy Silverado GMC Sierra 1500 2500 HD 3500 HD 2016-2018

Matches my all white build. I installed wrong at first so had to watch a YouTube video on the boostauto ones. Same as that. Directions in the box aren’t good, But works as it should and looks really good.

Installed on 2019 Silverado 2500HD. The lights fit into the mirror well. I watched a couple videos to get a better idea or what was involved in changing this part out. Only issue with the wiring harness is, make sure the colors match when you hook them up to existing wiring and part of my harness that connected the red wire from the new light to the wiring harness of the car, the red wires didn’t connect/weren’t lined up to make a connection in the plug. So I had running lights but no blinker. But quality seems good, lights look great and hopefully will hold up over time

Nice lights easy installation great fit good look

Lights were super easy to install after watching youtube video a couple of times. Everything worked as described and looks great.

Lights didn’t work. Instructions terrible. Connectors don’t match my housing. Gonna use a different brand.

I followed the directions and watched a couple YouTube videos but could not get the turn signals to work. Upon inspection of the adapters sent with lights I realized the plug that was wired backwards, black to red and red to black. I flipped the wires around on the plug and everything worked perfectly. I provided a picture of the plug as it was originally. Take 30 seconds to check that and it can save a lot of headache.

Very bright and visible. Glad I purchased. The only issue I had was with the turn signal connector. It didn’t work for my vehicle even though it says it should. I was able to figure that out though. Otherwise they are pretty nice.

If you’re confused about the wiring… 1. Plug into the new lamp exactly where you pulled out of the old one 2. Make sure the long red wire is pulled through and to the front assembly after screwing frame assembly back on. 3. Take included jumper and plug the black end into the long red cable (match the black ends) 4. Plug the white jumper and the signal cable together, (match the white ends) then plug the jumper into the back of the mirror. You should be good to go. Light will illuminate white when lamps are on, and switch to orange chasers when signal switch is activated.

Delivered earlier then expected. Easy to follow instructions but go online to watch video as mirrors can break easy. Video is clearer for removing mirrors. Product look great and signal light wiring kit was super easy to install.

The running lights worked fine, but the turning sequence does not work. I tried both adapters that came with the kit to be sure it wasn’t just me and neither worked. Additionally, the additional wire for the turn signal ends up being in a weird position in the mirror housing that it would not be good for long term use.

Drivers side light does not work. The pins for where the factory plug goes in it are pushed back into the receptacle. No issues with the passenger side. Guess I’ll have to return and hope for better quality control on the next one.

One of the lights does not work so now I need to take it off the truck and return it. Pretty annoying.

White marker lights work but orange signal does not.
