Here in the UK, and I suspect the rest of Europe, low beam is 55w and
high beam 60w. Sometimes this is provided by a dual filament 55/60w bulb
and sometime by separate bulbs. In the days before halogen bulbs, IIRC
the power was 45/50w.
You can get high wattage bulbs (I've got some 130w on the rally car, but
they are marked "not for road use", so at least in theory
illegal...assuming you get caught in the first place!!
Just a throw away thought - despite the stated power of the HL bulbs,
I'd bet a fair amount of money that 95% of road cars are actually
putting out considerably less. On my old Audi rally car, with the OEM
wiring the voltage at the bulb was ~10v c/w ~13v at the battery which
equates to less than 45w or ~20% less output - I'll leave those more in
the know to tell you whether that equates to 20% perceived less light.
We replaced the OEM wiring and switches with 32/.2 and relays - net
result was a noticeable difference in output and the ability to run high
wattage bulbs without the danger of burning out the switch gear :-)
