I30 Brake light problem

[Super Mario]

My '97 I30 has a brake light problem. As you all probably know, there are two brake lights on each side of the car. One is in the fender and the other in the trunk lid. The left trunk lid brake light does not work and I know it is not the 1157 bulb. Does anyone know how these brake lights are wired or where I might look for the problem? I cannot see how it could be the switch, since all the other lights work when the brakes are applied. I know this is only a nit, but it is going to drive me crazy until I get it fixed. Any help would be appreciated.
