Does anyone know what type of bulb to use to replace one of the fog lights? Also, how do you change it...from underneath? Thanks

Call your dealer. It may be covered under your warranty.

just had to replace one of mine its a phillips 9040 or GE H11-55 . they just twist to pull out and unplug the wires . its a little hard to do if it is on the ground . much much easier if u have a lift or a jack. :P
