<VV> back up lights out

[Charles Birchwood]

Hey all,
   so one of my LED 1156 back up light bulb went out on my '65 monza so I went 
to replace it. It took some muscle to get it out like it expanded or something 
in the socket. I bought some traditional 1156 bulbs to replace them since I had 
no LED available to me, now I can't get them to come on when the selector's in 
reverse! I have good grounding I know. Anyone have an idea. I checked all my 
fuses up front and none seem to be blown.
