I got my set today. I asked for a kit with shorter 12" LED strips. Threw it into my smaller safe and was done in about 15 minutes. The roller switch works really well with the safe door. Great kit.
Here are some quick pics I took. Not much room to hide the wires and battery pack, but I covered up everything in wire looms and used black electrical tape so it doesn't stand out. I'll think of something to use as a cover over the battery pack later.
