Is there a "light switch" on the sliding = door of a westy that connects to the back Light? It does not appear to have one. This is my daily driver and I thought I might wire the front compartment light to the rear light so when i open the door the whole = van lights up. Looks pretty easy, connect through the headliner behind = the rail that is above the sink stove and into the light. Has anyone ever = done this? Any special concerns? Looking for more light in CT.
