I have put leds in all of my dome/courtest lights the ones in the rear seat and trunk are easy to do the ones in the front of the car are a *****. I had to take the whole plastic piece that has the sunroof switch and lights completly off that was the easy part couple of plugs and clips and ur done. Fords stupidest design along with the bulbs in the side mirrors which is another story. to get the bulbs in i had to take the other ones out which popped right out casue its an easy angle to get to. To get them in is a hassle, there is a metal reflector to reflect the light of the two bulbs downward and it is directly in the way of getting the bulbs in. I had to turn the piece upside down and put the bulb resting on the plastic piece then flip it over and hope it lands resting on the brackets. After many failed attempts i got on rested on the bracket it still wasn't in i had to take a paperclip and wedge in there and push down on each side of the bulb. What you think is a simple job turned into an hour long job. Hope this helps...
