Further to Len's comments, I can just remember "big" cars with dash canopy lighting so the phasing out by 1958 seems accurate.I don't recall seeing a a photo of a W5 with dash canopy lighting. Perhaps Mal has one in his collection?
I don't recall seeing any W5 with dash canopy lighting -- but there's a slight niggle at the back of my mind. Considering that W5s (and some SW6s) ran the whole Sydney Rd service from Brunswick Depot after conversion from cable, photos of Elizabeth St or Sydney Rd would probably be a good place to start checking.
From the early 1950s, I clearly recall W2s 336, 442, 451 (also SW6 889) at Kew Depot with dash canopy lighting; also 607 at Essendon; there were of course plenty of others.
Can someone explain what changes were made to the lighting circuits to accommodate those two extra bulbs for the headlights? Standard headlights had one, dash canopy had three. Melbourne practice for lighting circuits was 6 x 120 volt globes in series per circuit (the nominal supply voltage being of course 600 volts, but running bulbs at less than the rated voltage was supposed to let them last longer). More bulbs in a circuit would make them dimmer.
Hal Cain, remembering the lights gradually dimming in the evening peak as the tram approached Mont Albert and the overhead voltage dropped
