light strip attached to Motor home below awning?

Weatherproof LED lights is what I'd use. I have LED's but they are not weatherproof (I coudl put 'em in a vinyl tube) Get peal and stick so you don't need to if you will pardon the pun.. Screw Around.

I got a strip off Amazon for a good price but the tape doesn’t last long. I got some 3M double sided automotive tape which has held for 2 years with no sign of letting go. I attached mine to the underside of the awning track that is attached to trailer and wired it into the porch light.

Be careful of cheap LED light strips. I used one and it failed in a year.

On my current TT I found a strip that came in a silicone sq. tube. It seems to be holding up nicely.

I also used a double sided tape to attach, but used a "butyl" tape from Home Depot, it's a little expensive but it is holding great! I also suggest to add a plastic cable strap that us screwed in at rfw ends, so wind and weather won't start to peel it up.

i believe AMAZON has a 16 foot strip of LED lights that are waterproof. They make an very nice looking patio.

You can use double sided tape.
Just make sure the lights are rated for out door use.
