Osram Nightbreaker and Phillips Extreme Vision are both well proven bulbs and highly regarded as upgrades.
Available in all the headlamp fitting types, probably H4 in your case, which is a twin filament bulb for dip and main. Other types will require a separate bulb for each beam.
I prefer the Osram, which is a little cheaper (read less expensive) and has the reputation of lasting longer. There is very little difference between the two in reality.
I heard of another bulb today, by Halfords called the Halfords Extreme something or other.
A lower price and even better performance than the above was reported, but as yet untested by me.
I've just bought a pair of these, as yet untested but looking very promising indeed. I'm already getting on very well with a bulb of the previous generation to these.
