len, like someone else said, what has driving time got to do with what I know, I dont know how long you have been driving, so I will tell you about myself (not that it matters) I am 37 and have had my driving licence for 20 years (long before hids were around!) and I have also had cars with mega high wattage bulbs to try and improve the lighting, and what I find is, apart from being illegal, dont work that good, they risk frying your wiring, and all they do is make the light more oranger if you get what im saying, they also annoy oncoming traffic as they blind them which is one reason they are illegal, I know there are plenty of people who really dont care if they are illegal and blind other drivers, but hey, you dont like it when you get dazzled! I think maybe you should read up about light output, and the different tempertures they output, and hids output at a different spectrum which in laymans terms means, that they output a different colour, which is more closer to natural daylight. if you goto certain electric shops, you can buy natrual light bulb which are blue in colour, but outputs a pure white light. now cos of this, hids are more whiter than halogen, which means you can see better, which makes your driving less stressful on the eyes, they also work at lower wattage, and they also seem to go further than halogen.
Now I know they are more expensive, but hey is a preference thing! but its like some people are happy with a 8v gti, but some strive for a vr6, but at the end of the day, you proberly go the same speed in this gatso infested country, so why pay more for a vr6? its a preference thing, if your happy with your twin hellas, then fine, no one should knock you for your choice, but some people rave on about hids the same as you rave on about your twin hellas! hey if we all like the same thing, it would be a boring world and we would all be driving mondeos
