how hard to put in...cost etc...your very tight on info here..lol
Not hard took about 15 minutes to install, luckily on the heritage F150 everything for bolting and wiring is within reach. The only thing I had to do was remove lenses, but you have to do that to replace regular bulbs anyways. However because I didn't have the tool my wiring is exposed for now, but when I get the chance I will hide wiring and remove overflo coolant tank so I can hide the install completely. I also swiped my Stealth bulbs from the '06 to install on the Lightning for now. A second set is on the way, but I bought from an ebayer who likes to sell stuff he doesn't have in stock yet.
Oh, and the problem I had with aiming was I didn't put the passengers side all the way in....oops
