I have replaced all the exterior lights on my camper with LEDs, and also the blue front cap light strip. I have also replaced the awning light strip.
The trick to the successful change of the cap and awning strip lights is, do NOT use the ones sold by the dealer as replacements, they are expensive garbage.
I found all my lights online, the majority at superbrightleds.com.
They are all 12 volts, so easy to match up with universal replacements. There are many options.
I even made my awning lights multi-colored, multi-function, remote controlled.
A little research on the site, you'll find what you like.
