You'll see a big difference if you went from halogens to HID's but even a bigger difference when they're cleared up. Once you get the outer part clear, you can see what the chrome looks like. If the bottom only is burned, it's not that big of a deal. Any backside burn is what takes away. I know it's a high price but if you can get new ones, it's well worth it and no more worries about burning the chrome with a 35 watt HID kit. They'll last you as long as you own the car. I'll go out in the garage in a little bit and get some close up pics with them on. I have a pic of the brights and lows on at the same time. The low beams at the time when I done this were 8000K and then I tried 12,000K and then went to 10,000K and just last week I put in the 6000K I have had put back.
