I have done more research on the lighting upgrade/relay issue...

Headlights: According to Haynes and the Pelican catalog, the USA stock sealed beam headlights are 55/60 watts, high and low beam...same as Hella H4 units with the 'stock bulb' (55/60W). It shouldn't make any difference electrically speaking, which lamp is installed. If there are heat-related problems in the switches/relay/wiring, then the car has other problems and while a relay may appear to solve the problem it really only masks it. I would think then that it should be ok to use the 55/60W H4 lights without a relay. Relays/fuses would be required to increase the lamp wattages from their stock wattages. As an aside, I don't know others experience, but when I had the H4's (55/60W lamps) installed for month or two, I didn't notice much difference in the lighting quality or characteristics from sealed beams, nor heat problems either.

Fog/driving lights: The stock lamps are 35 watts. H3 lamp upgrades are 55 and 100 watts...relays/fuses are therefore required.

One other thing that hasn't been said is that relays need to be installed for the headlight high and low beam circuits as well as the fog light circuit if these stock lamp values are exceeded to protect the wiring and switches. As many as 3 relays in all may be needed for a 914 lighting upgrade.
