Just buy 2 LED strips off ebay/amazon and about 10 feet of extra cable and DIY it to your dome...$20 and 20 minutes. This way you can even choose the color/brightness. No tools required besides wire strippers and electrical tape. Scissors can replace the wire strippers if you don't have any. The FRS interior is the easiest I've ever worked with. Almost everything
pulls right off. Wires were so easy to tuck that no one will every know.
No mechanical background needed...
