Wade, the Hella USA site has DOT approved versions. The non USA Hella site has the ECD (European) approved lights...Many run them here. Some claim the E code lights tend to get into the car ahead of you in the right lane when you are in the center lane...
Reading Daniel Stern, he seems to believe that the quality lights like Hella are good in either version and does not have a problem with the E code lights. Stroker has them, and I have used them in the past and liked them. They were far better than our lights a few years ago altho our lights are much improved today. I consider either better than the cheap HID conversions with the sorry reflectors that are not designed for such.
