Review on Partsam 5X Amber 24 LED Smoke Cab Roof Running Top Marker Lights 264146BK Assembly Wire Harness Replacement for 2003-2018 1500 2500 3500 4500 5500 Pickup Trucks by Brian Wesley

These lights were better quality than stock. I had to replace it because the lenses were 3/5 cracked and water got into the cockpit. The electronics were high quality and well sealed compared to stock, easy to install and plug and play. If it doesn't light up, rotate the back that plugs in 180 degrees to find the correct polarity. DO NOT overtighten the screws. tips. I used flexible tape on and under the roof and routed the wires through an "X" that I cut out with a utility knife to prevent future leaks. Also, the base and screw holes were coated with silicone on the outside, as well as the clips on the inside where the screws went through the roof. Before connecting I applied a drop of dielectric grease to prevent further corrosion and ensure a good connection. The biggest PITA was the removal of the headliner and jambs. The main thing is patience. The same applies to additional small steps, e.g. Silicone. This product uses high quality screws and silicone and should last indefinitely. Looks great, very bright and directional. On the other hand, if you decide to cut the flexible caulking tape after it's applied and peel off any excess, it's going to be a mess! My girlfriend now knows what we girls go through when epilating. Yes, it's a little hairy on top, but I don't care, you don't see it, and chances are this thing is NO MORE LEAKING! Great design, better than stock, easy to use, worth the money. PS - the screws go in NS, not EW, in case anyone is interested.
