I was just able to fix this issue on my 74. It seems the previous owner's fix for a broken switch was to tie-wrap it to part of the headlight so it wouldn't hang down??? Some fix! Thanks to some direction from WetVet and T-Mans70,73 on our cruise to Stonehenge, I was able to locate the switch, order one and fix the problem. It happened to be the driver's side switch that had sheered off. I've included some pictures of the new one in place. Thanks a lot guys. That annoying light is now gone...

As seen from laying under the front end, looking up through the access hole...
A little closer view...
A little closer, although blurry... Notice the little plunger that gets pressed down at full open, turning off the interior warning light.
Installed and fully functional. Thanks again C3VR members...
