Hi guys - now that winter's approaching , I was thinking of uprating my bulbs on my twin headlights. My idea was to get some Osram Silverstars for the dip and some bigger wattage for the mains. Would I have any problems with the wiring if I went for something like 100watt bulbs on these mains? Is the circuit protected by a relay?- I remember having problems many years ago when I upgraded a Dolomite Sprint - It went on fire in the vicinity of the ignitian barrel (overloaded circuit).
