I took a white, surface mount LED from a retired sled, and put it inside my pickup bed on the wall. I wired it to my door circuit and I use it for a bed light, so I can see what I'm doing at night while loading/unloading. See, they do have a purpose.
Just use the ground wire to tap against a ground point, it will cycle thru all the different flash patterns each time you do. I just did that until I got to steady burn, so it acts just like a regular led light. Yeah I'm cheap, ...or green for recycling.
