have searched "keyfob"here and have read all sorts of interesting stuff, button ignitions, how to get into your car with dead battery and failed key switch, etc, etc, etc. at the risk of perhaps causing some belly laughs from those in the know, i would like to know what if any function is served by the red lens like piece on the key hinge end of the fob. it looks like it could contain a light bulb, but if it does, i can't figure out how it is activated. if it is "decorative" it could be the recipient of the "stupid part of the year" award for serving absolutely no purpose, lol.

thanks for solving this great mystery of the universe for me!!
