The interior lighting is LED based. This follows the decision to go with LED lights everywhere possible. I believe the only non-LED lights are the head lights. These are HID bulbs. To me this is a proven technology as I have applied it to the Corvette and the Porsche.

This the hole for the switch.  This is drilled through the fiber glass and sheet metal.

  Of course, this is a GTM so there are still other things that have to be built to make interior lights work. I purchased the door jamb switches from Quick Racing Products. There are a lot of great products on this site. The switch is installed in the door. This is just the signal circuitry to the master cell. The power lead comes from Master Cell #4/Circuit 10 and this routed through a hole cut in the front fire wall.

The QRP door jamb switch installed.

The first thing that needs to be figured out is where the switch can be installed on the door. I determined that there is an average of 3.25 inches from the axis of the hinges on the frame to the edge of the interior body shell fiberglass. There is a 1 to 1.25 inch gap between the frame hinge and the start of the body shell fiberglass. This leaves about a 2 inch strip where the switch needs to make contact. I took door and measured 2.5 inches from the hinge on the door (this will vary from car to car) and checked to make sure there was fiber glass and not the steel hinge plate behind it. This is where I drilled an 11/16 inch hole for the switch.

Terminal block with signal wire from the master cell to the circuit.

I piggy backed the ground and signal wires through the same wire loom used for the door poppers and windows. These connectors are all wired through Weather Pack terminals.. I plan to have to use large diameter wire loom as an over all shield in the gap between the door and the car. The signal wire runs through the internal conduit above the tunnel and interfaces to the other signal wire (from the passenger side) and the signal wire to the master cell via a three position terminal block.

Under dash LED pod.

LED lights are three pods installed above the passenger and driver side foot wells. It is very busy under the dash. I used a strip in the Corvette to replace the bulbs. However, I didn't feel a strip would work in the GTM environment.
