I'm new to the forum. I have had my 2011 Sonata SE for about 2 weeks now and I love it! I've been reading up on HID kits and decided to order some. I bought a 8000k w/ relay harness from hidnation. Installation was pretty easy, but when I was driving home after they were installed I noticed the left headlight had a very slight flicker to it. It's now bugging the crap outta me!. I saw that cancellers will prevent this from happening, should I go ahead and order one of those? I also saw on this forum that cancellers arent needed for a 2011 sonata but a relay is needed and vice versa. Can both a relay and canceller be installed? I don't really know what to do. I would appreciate some feedback, thanks!
