There is a noticeable difference when you drive a vehicle with HID's and then one without. It's amazing when you get back in a car without HID's as you've never really appreciated how yellow your headlight beams actually are until you drive a vehicle with HID's as the light beam now appears white. You should be able to see things a little further away and you should definitely be able to see things more clearly. As far as kits go, I've heard pros and cons on them. The con argument is if you put an HID kit in a vehicle that did not come with HID's, the reflectors are not set up properly for the different light source. I imagine this means you will be more glaring to other people on the road. I've only had experience with one kit and it wasn't a pleasant one. One light would work great but the other side would overheat or short out or something and fizzle out after a few moments. I got it from a company in Canada too and had to deal with the hassle of returning them to customs. Other people's experiences may have been better, but I'm not willing to bite again. Good luck with the surgery!
