I already installed one in the glove box, but I used the 300C/Magnum/Charger glove box light as I knew the part number, knew what it looked like and how it worked. Part number is 04565022 and its like 6 bucks. Plus the Charger/Magnum in all trim levels, even SRT8, and regular 300 (non-HEMI) don't come with it, WTF?! even though the wiring is there and there is an indentation in the shape of it as a template to cut out the hole for it, so I had bought one and installed it already.
Next up I am going to use the old Cherokee under hood light twice over, to put a light under the hood, and to put a light in the center console. This is the same light used in older Dodge Dakotas and the Charger Police Package as well Part number 56021441 for 12 bucks. It has a mercury switch in it that completes the circuit when it is tilted, as in the hood or console cover being lifted. Already added it to the Charger, and since it comes as part of the police package, there is even an indentation in the silencer pad, and hole in the hood ribbing for it to be installed. I can easily adapt it for the Liberty as well. Just haven't gotten around to it. Did I just give away ideas for mods before I did them myself? OOPS.
