I thought it must be a bulb as I have not seen a one piece molded into plastic light bulb. try spraying the bulb area with WD40 or some "break free" from a can- a little oil will not hurt plastic. You can then GENTLY try to remove it with pliers-try a twisting motion. Again look in the owners manual and it will tell you the bulb number. or buy them in the last link I gave you-it has them form 5.00
