If you are talking of higher wattage bulbs, it's not really the lights you'll need to worry about, it's the wiring. ANYTHING above standard wattage means more current, and with the car's stock thin wiring, you're pretty much wasting your time, unless you relay the lights, and that would mean new wiring for both dip and main, and at least two relays.
Have you looked at so-called "uprated" bulbs, like Halfords 50% or 90% uprated, Philips 90% and Osram Nightbreakers? They DO produce the results of higher wattage bulbs but still draw the same current as a standard bulb.
An added plus is that the bulbs suggested above are optically accurate. This is VERY important, since tests have shown that poorly designed, or manufactured, bulbs scatter light terribly. It has been shown that a GOOD standard bulb actually appears brighter to the driver than a poorly made 100W bulb.
Halfords bulbs are BOGOF at the moment, and the other two are available off the net for around £18 a pair delivered
