do you have a high beam or dip beam warning lamp on the headlight shell? i'm questioning my 66 spitfire - has none.
my 66 instruction manual shows a lamp and also the wiring diagram, however the parts manual shows none.
If it's the same as '66 Triumphs, early don't have any idiot lamps, middle have one, late have two ...
fitted my bike with a later headlamp shell with the later toggle switch, ammeter and warning lamps for oil pressure and main beam.
would like an oil warning lamp
Red idiot lamp wasn't used for oil pressure warning 'til '69-on; before that, the bulbholder just had a White wire (so energised when the ignition switch is turned on) and a Red wire, so the idiot lamp was just an 'ignition on' warning.
When two idiot lamps were fitted, it depended which colours a given production-line worker pushed the bulbs into - a bike could have red 'ignition on' and green 'high beam' ... or the other way 'round ...
