great - that answers my other question - it was a column mounted dipswitch ! Thankyou.
In Aug 29 handbook its plainly the same switch panel, but switch panel right hand switch refers to second position (S) as "headlamps dim and tail lamp" and position 3 (H) as "headlamps bright and tail lamp"
I'm now wondering what the earliest pilot bulb occurrence was. Is this dim headlamp just the pilot bulb?
