The original lamps could be focussed quite sharp which was OK on the roads of the time but now need spread light to find marked lanes, traffic islands, far distant edges etc. Modern lamps like the semi sealed BPF conversions disperse light so need lots of watts.
Curious about the 25/25 halogen. On another car with semi sealed BPF I purchased halogen bulbs but the patterns were ludicrous and unusable.
Incidentally very few original sources give original lamps in watts, just candlepower, and this has not deterred the innocent use of much larger bulbs, often killing the dynamo. (For BPF conversions used to be able to buy 21w vertical dip motor cycle bulbs)
Brake lights were 3 (three) watts! Just as well could not pull 1G stops. No point in taking foot off the pedal at lights!
Am curious that only one lamp dips. Is the old Brit sytem of one lamp extinguishing still permitted? Was banned here about 1960 and my RP seems to have always had two (diabolical) solenoid dip lamps, certainly since 1940.
