It'* fairly easy.
You will need a 10 mm socket, 6" of extension and a wratchet. Just at the grille side of each headlamp assembly you will see 2 bolts pointed in towards the engine. Remove them.
With those 4 (two on each HL bracket) bolts out pull the inner end of the headlamp out slightly and then push the assembly towards the side (across the light mounting position).
It will be kind of a pain (I actually had to give up on my drivers headlamp as it absolutely refused to come out. I ended up with a left High beam bulb pattern pointing over the garage from 20 feet away.
