Dome light upgrade from DC to AC power.

I wanted to up grade my dome light from battery power to AC power. I'm not planning to use battery to power anything in the trailer, but I still wanted to use the dome light. Fortunately, the original wiring was still run from the light, through the ceiling, and into the cabinet. 

Here's the original wiring coming out of the ceiling and the cabinet. When you remove the light fixture from the ceiling cut the wires . Don't pull them through.

I wanted to still use the original fixture and globe, so I needed a new light that would fit inside the old fixture. Here's a picture of the two lights side by side.

I purchased the new light at Lowes. This is a picture of the new light still in the package. The power cord plugs into the light instead of being permanently wired. This makes easier to fish the wire through the ceiling.

You can see how the new light fits into the old fixture.

The cord was just long enough to reach through both holes.

Tape the old cord which is still in the ceiling to the new cord.

And pull the old cord out of the fixture end until the new cord comes out.

Unfortunately, you have to open the cabinet door to turn the light on and off. I also added an outlet in the cabinet to plug into. I'll cover how I did that in a future post.

You can see the wire is run and ready to be plugged in.

Plug the cord into the new fixture.

Mount the new fixture to the ceiling. Don't use screws too long. They will poke through the roof skin. You can see the lighter area on the wood where the old light was located. Make sure you mount the new light in the center.

Now reinstall the old fixture over the new light.

I thought new light would fit in the old fixture with the old globe, but I couldn't get it to work. If you don't tell anyone, they'll never know.
