I've done complete LED replacement for the turn signals front and rear, the side markers front and rear and the "horn" lights above the headlamps. As Tom said, just a simple wedge replacement for the OEM socket would be very easy but not very bright, unless that is what you are after. Here's the link to the write ups I did in the Review Section. There are some newer, brighter choices for LEDs out there and they keep getting brighter, but I still haven't found any that can out shine my 100 watt DE's or the HIDs that some have put in.
