Re Duncan's comment about 4 x 55W headlights etc.
In 1969 as a young single man I bought a VW Beetle – 12v 40/45W headlights. 1st upgrade was to fit higher powered bulbs, 45/60W I think they were. Next was a pair of Lucas LR6 spotlights which came on with the main beams. And finally, a pair of spots for use as foglights.
Now fast forward to 1998 when as a middle to old aged family man, I bought a 1996 Peugeot 405 estate. This car was fitted with, as standard, a normal pair of double filament headlight bulbs, a pair of spot lamps which came on with main beam, and a separate pair of fog lights. In other words, its standard lighting was exactly the same as the Beetle I modified 29 years previously. Which shows just how much lighting has improved over the years.
As it happens, I didn't realise that the Pug had twin spots until I had owned the car for a few years and one of the beams failed.
Interestingly, my next car was a Focus with what seems to me to be somewhat retrograde lighting. Whereas the Beetle and the Pug were capable of supplying large amounts of main beam lighting by having in effect four main beams, the Focus used dip beam and only two main beams, so four beams in total, but only the two long distance beams. It wasn't anywhere as good as Pug. Furthermore, it suffered due to a cack-handed MOT mechanic who insisted on lowering the beams until they were next to useless on main beam, this in a rural area with next to non-existant street lighting. Eventually, after much complaining, his boss put them back as they should have been, but still within the MOT guidelines.
And again following on from Duncan's comment about the M62, I had a deeply unpleasant journey one Friday evening, in winter, in rain, on a MZ250 m/c with 6v lighting. My route was Stone (Staffs) – Stoke – Leek – Buxton – Chapel-en-le-Frith – Glossop – Huddersfield. Those of you who know anything about that route will know that it includes some quite high unlit roads. Understandably, my return journey the following Sunday evening was by car.
