I went with Silverstars first. They were a big improvement, but nothing like the E-Code/H4 setup with a harness I switched to a few weeks later. I can actually see, and not blind oncoming traffic. I don't like stock HIDs, so I definitely didn't want aftermarket ones (just my opinion, I think they're annoying). E-Codes may not be DOT compliant, but I haven't had an issue in the year I've been using them.
