OK so I have been working on my daughters 68 truck getting it tore down. I took the grille apart and pulled the front parking lamps off. They are basicly the same thing as your bumper lights just mounted in the grille.

So any way I decided to check them and see if they worked. One did the other one wouldn't hooked to my battery. I used a jumper wire to the pigtail and another one to the mounting bolt. Nothing. Took the bulb out and checked it. Broke the bulbs both trying to get them out.

So I got to looking inside the socket. The double wire insert was stuck in the bottom no springing action. I soaked it down good with PB blaster and used a small screw driver. I could push down but it wouldn't spring back up. I cut the rubber right at the housing on the back side and used the small screw driver to punch it up. I worked it back and forth until it would spring back on it's own. I will tape the rubber back down to the housing but I got it working. Both lights work fine now. Hope this helps you on yours it may just need a little push.
