E46 Convertible Third Brake Light: Notes

The E46iC from 2002, uses Neon technology for the third brake light which is mounted in the trunk lid. The remainder of the exterior lighting circuits carry over from the E46 Sedan and Coupes. The Electronic brake light switch is the input to the LSZ for brake light activation. The LSZ, as an output, provides power to the Neon light module for activation of the light. The light module consists of the ignitor, and Neon tube.
