Bill I havent seen behind the instrument cluster in our car so initially I wasnt sure the dimmer was part of he headlamp switch - tho as it's controlled by the same knob, I now realise it would be. Then I looked back at some pics we were sent tp://s65.photobucket.com/albums/h233/rob426uk/63%20instrument%20cluster/ (hope the link works?) by the people that sold us the spare cluster that we have had sent to Autoinstruments, and saw the headlamp switch looks like the one Jim sent me a link to (thanks Jim!). We've had similar problems with our 69 Sport Satellite - that has the separate thumbwheel. Sometimes that takes a few rotations back'n'forth to get the lights to dim/brighten, but they're still pretty dull at the best of times. The guy at Autoinstruments offered to test the resistance on the dimmer on the cluster they are restoring, but asked "We can tell if it works but we may not be able to tell if it will let the lights get bright enough when it is installed because we don't know what the resistance readings are supposed to be. If it shows 0-80 ohms we'll know if it works but what if the switch is supposed to be 0-100 ohms? Do you know what the resistance readings are?" Can anyone answer this?
