JW51 You should have 5 lamp sockets under the dash 2 for the gage cluster 2for speedometer cluster 1 for key mount bracket so you can turn on dash lights to see where the key slot is. The 2 clusters have snap-in holes left and right,after practice you can reach in with one hand and change the bulb. Headlight knob counterclockwise dims CW brightens,probably be kinda coroded at first will get better. I take a can of WD forty, remove knob and stem by depressing that button on top of the switch,just pull it out-insert your WD 40 tube as deep as it will go into the switch,spray on your way out. This will lube the switch, lube the point on your stem push back in will re-engage the switch. Might spray the rheostat coil at the front of the switch too.
