First you will need a 1/4" ratchet, a 12" extension and an 8mm socket as well as a telescoping magnet. You need to remove the headlamp to change the signal bulb. You WILL need a new bulb AND the turn signal socket assembly (from the dealer) as the socket is what causes the failure of the bulb on these. Note which color your signals are- either clear or orange as the dealer MAY need that info. To remove the headlamp- remove these 4 screws marked by the number 2 using the socket setup above. When the lower screws are loose- put the magnet against the screw so it doesn't fall into oblivion. Install the screws using the magnet to start them then tighten to the original location (you can see indentations from the screws after you remove them) You the slide the headlamp forwards and towards the grille to unclip it from the front fender. Once it is unclipped- you can access the signal bulb and socket. The plug for the socket is right behind the signal. The socket simply twists out of the headlamp. The socket wire is unhooked by pressing on the release button. (look at the new one to visualize this) It sounds like a lot of work- but it really isn't that bad.
Hope this helps you out!! --Cliff
