[TenTec] Centurion dial lamps

[Ken Brown]

The intermittent character of the problem suggests bad contacts in the 
bayonet bases. Replacing the incandescent bulbs with LEDs would not fix 
this, although the lower heat produced by by LEDs versus the 
incandescents could change it, maybe making it last longer between 
failures. I suggest DeOxit on the contacts. You can buff the center 
contact on the bulbs too.
