Ulysses Trunk Lights
I added a series of lights to my trunk. Two strands of SMD5050 White LEDs went under the reflector, and one strand of standard White LEDs went inside for interior lighting. The rear facing lights are 'single filament', but I split the wiring, running one wire through a flasher module to the brake light power source, and the other through a diode, and resistor, ending at the tail light power source, allowing them run dim like a tail light, and then flash to full brightness for the brake light.
The switch is a fairly standard microswitch with a lever. I ran the wiring beneath the weather stripping for a more stealth look. When the lid is opened, the switch opens turning on the interior lights. It is wired through my Auxiliary Electronics Control Module, and work whether the key is on or not.
