Anyone upgraded the bulbs on their gta? (for those of use too poor to have Xenons

) Anyone tried those blueish bulbs?
Would like to improve the light from the car as I dont think the lights are particularly bright. In fact, I was never impressed with the light generated by any Alfa I've owned.
Thinking along the lines of this stuff:
Philips X-Treme Power H7 from Power Bulbs
Worth trying for £30 I suppose
