Here's another pic after I drilled the hole and hadn't made the wires longer.
I have to park in some less than desirable locations every now and then. Instead of springing for an actual alarm system I thought a cheap deterrent would work well enough. I don't keep anything in the truck but would rather not have my window broken.
I just bought this light on Amazon. The wire wasn't long enough so I desoldered it from the board and soldered on a longer one, then wrapped the connection in heat shrink tubing. Drilled a small hole in the back of the glove box and ran it up to the top right speaker panel and drilled a hole in the plastic for the light to poke out of.
There is a switch that turns it off and on in the glove box and it's supposed to last 1.5 years with 2 AA batteries. The whole thing turned out really seamless and thought I'd share.
