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).
๐ 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.
