1. Just to clarify I didnt put the LED on the "tracks" where I live we have these large braces that run horizontally for hurricane protection. Thats what I stuck the tape to otherwise just stick them to the door like the kit. What I did looks very similar to the kit but you can buy the parts much cheaper.
2. I did use the waterproof lights even though they dont "need" to be water proof but they have a nice thick protective rubber layer over them. This helps protect from getting hit or something. I did this many years ago since I had a few rolls of the LED tape from another project and was trying to find a use for them.
3. I wanted to be able to use the lights when the door is opened or closed and didnt want to have a cord reel hanging. So I just ran some extension cord along the tracks and left a plug end near the fully open/closed position. I mounted the LED driver directly to the upper right corner of the door and put a short pigtail on it that could reach either of the 2 plugs. This does require me to manually plug it in if needed but I have lots of light normally so its not very often I use them. But when the door is open it blocks a good amount of light and when finishing it provides a good source of low angle light with the door down.
4. In case you want the automatic version the switch they use is is called a Dakota magnum shooter they are about 20 bucks. You will need to fashion your own bracket to hold it but it looks like you will save yourself a nice down payment towards some festool stuff.
