This thread will give you way more than you need, but the first few pages detail some options for mounting the LED strip under the edge of the awning, which allows them to be permanently mounted.
My solution to awning lights
Just be aware, these things aren't the most durable, but they are cheap enough on e-Bay that you can buy a new strip every couple years. Lots of choices - white, multi-colored, dual light strips, fancy remotes... They all install pretty much the same.
