i didnt use hid, rather led
got them from headlight revolution, who said they actually test them
i already had clear lenses
light scatter yes.
The problem with LED bulbs and to an extent HID, is that the lenses are not designed specifically for HID or LED. Then, the bulbs themselves are not the right depth, the LED diodes are on the sides rather than wraparound so in a stock lens the light isn't reflected the same way it would be with incandescents. With that said, they are 1,000,000 times better than even the best incancescent bulbs I could get locally and I tried them all. Only issue I had was that the connectors were junk and I had to modify them to properly connect to the vehicle harness, but it was easy and took maybe 10 seconds per connector. Check them before final installation.
