Swapping LEDs in for the turn signals (front or rear) will cause what is called "hyperflashing" and can be corrected with a load balancing resistor for each bulb. Resistors available at most auto parts stores.
2008-2012 Gen7 require you to partially or fully remove the front bumper cover to get the headlight housings out. They hold the headlights, turn signals, and front side markers.
Taillights are simple: inside trunk pull back carpet, remove 3 thumbscrew nuts, pop light out, R&R bulb(s). Reinstall in reverse. (Or park...

) (or garage... sorry, just that kind of day...

)
Rear side markers are somewhat of a challenge to remove but you can do it without loosening the bumper cover if you don't mind getting some scratches on your hand.
Interior dome lamps are easy to change. However, sometimes they will flicker when they should be off. Fix=add a load balancing resistor or keep at least one regular (incandescent) bulb so the BCM will be happy.
Instrument lamps are actually already LEDs! (Surface Mount)
Door handle lights are LEDs.
Overhead console lights that illuminate the shifter area are LEDs. (I changed mine to red.)
License light is a bit of a challenge to change. Search forum for instructions.
Trunk light is fairly easy to change.
There is no glove box light. (Dang, there's a place for the switch but they conveniently forgot it!)
