Attaching LED Strip Light To Dome Light In Enclosed Trailer

Question:

I am trying to install LED strip lighting inside my trailer using the existing dome light as the switch. My intention is to run them off the truck battery when the truck is on. Will the strip lights work when ran to ground or do they need the - negative voltage?

If the light you choose is a 2-wire design like the Thinline Opti-Brite LED Interior Strip Light, part # ILL71CB, you will have a White wire and a Black wire.

The Black wire would be attached to your 12-Volt power source, and the White wire needs to be grounded to a clean metal surface.

To be able to use this light and have it controlled by the dome light you will need to attach the Black wire to the wire between the dome light switch and the dome light.
