Trunk light

Will see if I can get a # 1004 bulb. I thought that the # 1176 bulbs glass was larger. The # 1176 was the only single filament bulb that had the lower locking pins. I can order a # 1004, but will.see if one of the stores can get it. Will see if that socket will come apart and see what's going on with the spring.
Thanks again, will let you know.
