Hey all! I give you full permission to snigger whilst answering this question but I'm sitting here with one of the front courtesy light bulbs in my hand that needs replacing and apart from ascertaining that it's a "festoon" type of bulb and 12V10W I'm lost. The measurements I'm finding online don't match this bulb. I'm measuring 35mm in length and maybe 9/10mm in width. Help! Please!
