Review on 🚦 Premium 4" Round LED Stop Turn Tail Back-up Reverse Fog Lights Set with Grommet Plug - Truck Trailer RV - FREE Sales Tax by Alex Panda

The headlights themselves are good but the installation was PIA. They don't make it very clear which hole you need for them. You might think these sizes would be standard. I have a knapheid on my truck, which is pretty typical for New England. All existing lanterns were 4 1/8 inches in diameter. I suspect this is the same as most generic bodies. These lights require a 4.5 inch hole. Someone in reviews was good enough to post this. I was able to drill all the holes and mount the headlights, which isn't too difficult, but I expected to spend about 10 minutes changing the headlights. Instead, I spent about 1.5 hours cleaning the taillight and taillight holes. Not the end of the world, but something to be aware of. Not everyone has the tools to do this. You'd be there for hours if you had to do it with a round hand file. Another thing is that the headlights are good. I would have given them 5 stars if it wasn't for the installation process.
