These lights are awesome. I've got a 25 F 150 to which I added these lights. They act as marker lights and directionals too. I ordered mine straight from Starkey. They offered 2-day free shipping plus in my case anyway, they did not charge any sales tax. The price was the same on Amazon but they would have charged me tax and would take a week to ship.
Some install notes. Watch the video Starkey produced. As for my vehicle, there is a hefty amount of foam insulation just inside the vent. I took 2 paint stirrers slid them in and opened up the gap so it was easier to feed the wire. Their written directions also say to feed the wire through the upper hole closer to the rear of the truck. A little snug going in, but once up there they fit perfectly. I don't think they mention which hole to use in the video.
As for the connections, it was pretty straight up. Please check the type of connectors you have. On my truck headlights there were red locks that slide and once unlocked, the black tab is depressed and the connection wiggled free. I snapped the red tab off one of mine and it cost me another 2 hours trying to figure out how to remove that connector. Once off it was easy to finish up.
These are a bit pricey, but the wiring harnesses are top notch and compared to the Ford wiring, well it looks like a kid put the Ford together and a true pro made the harnesses. You get what you pay for!
I got a pic and a video on the reviews on Amazon. couldn't seem o load them here.
