Converting to LED lights to the outside of your rig

Like BarneyS I just some off ebay and switched out the bulbs...easy..I see no reason to replace the entire lighting unit when you just swap out bulbs.

I am thinking about changing all of the exterior lights (brake, directional and marker).

On my Truck Camper I used all new light/assembly. Did have to scrape off some old sealant. Wasn't difficult. My manufacturer did not completely seal the front clearance lights on purpose. This was to let water out. I completely sealed them. No intention of removing or replacing the LED replacements.

My problem was with the lamp outage system. I had to install ballast resistors.

I did every one of my marker lights last winter. Simple to do. Just pull off the lens, pull out old bulb, insert new bulb, and replace the lens. Here is what I used for the marker lights. They are short enough to fit under the lens cover and the price was right (20 for $7.49 and free shipping). :) I also replace all the ceiling lights in the trailer with these.
In addition, I replace the regular bulbs in three fixtures with these cob style lights. I am very pleased with the color and light output. It is almost identical to the regular bulbs in color but a bit more light output.

I did not replace my tail/turn/brake light combo.
My buddy did his and has had a problem with the LED's burning out. I don't know who the maker of his was.

Running lights or house lights? Either one is not hard to do, by replacement led bulbs or new led light fixtures and install. Might need to clean off some old sealant and replace with new around the new light fixtures.
