2014 Trilogy - 3850RL - Customer Panel Lighting

One minor issue I have with my Trilogy is the inability to see the switches and labels for the customer interface panel (where all of the awning controls, slide switches, etc. are located.

Today I installed a simple modification to illuminate the panel when I open the door and extinguish the lighting when the door is closed.

This is what it looks like when illuminated.

You can see a wire hanging down in the upper right corner . I was anxious to test this and get a picture taken. Tomorrow I will finish dressing the wiring so it does not show.

This picture shows the first half of the switch. It has terminal connectors on the side that is hidden. I ran +12V dc to the COMMON terminal and connected the + lead of the LED strip to the Normally Closed (NC) terminal.

This next picture shows the second half of the control for the lights (right hand side).

There is a magnet inside the block that is mounted to the door. When the door is closed, it activates a switch (due to the magnetism) and OPENs the circuit, turning off the lights. Circuit is OPEN. When I open the door, the magnet is no longer holding the switch in the OPEN position, so it goes to CLOSED and the lights turn on.

The two components are usually found in a home alarm system. When a door or window is opened, these are the switches that make/break the circuit and set off the alarms. I just adapted it for my lighting of the panel.

Bought the switches on Amazon ( : Magnetic Switch : Automotive Door Jamb Switches : Car Electronics)

I plan on implementing more of these to illuminate other cabinet interiors. I hate having to get a flashlight to see in the back of a cabinet

Awsome mod John. I have been toying with the idea of lighting some cabinets but did not think of the panel. What a neat solution.
