After having refractive eye surgery I can tell you exactly why you are not supposed to use HID kits on cars not designed for them. You could be the cause of serious accident, especially on backroads. You may think it's ok and you can see fine but I can tell you right now you should take serious thought for others first. Dipped beams are dipped beams for a reason, you don't even need HID most of the time.
You might get away with using HID's on the GTV purely because of the style of headlamp, and its restrictions, but it does not neccessarily mean its ok. There are loads of sources that all say the same thing about aftermarket HID conversions and that they are illegal. Put simply the lens used for the dipped beam is not designed with HID bulbs in mind, but has been designed specifically for standard HB3 type filament bulbs. That includes the GTV/Spider.
I'm a little surprised an MOT tester passed a car with an HID kit fitted.
Also, there are plenty of decent HB3 bulbs on the market. Your best bet is to avoid filtered type bulbs (blue filtering just reduces light output) and try going for a clear halogen xenon type bulb. They should be sufficient. If you need more light in fog then upgrade the fog lamps.
To err is human, but you need an Alfa to really screw things up!
The road to heaven is paved with old Alfa's.
