We bought a set of the heated lights and apparently got a bad set. Drove up in the mountains during a snow storm at night. Had to stop every couple miles because I couldn't see anything. Lights looked like a flashlight behind a piece of paper. Contacted TL and they sent out a new set the next day. Great customer service. Snowed the week after the new set came in and no problems at all. We did get the anti-flicker just because from what I have heard, some flicker, some do not, wife gets headaches from flashing lights so it was easier to make sure we didn't have a problem. Only issue was they didn't seem to fit as tight as the factory lights. The securing ring tightened all the way up left them just a little loose. I put a couple pieces of electrical tape in the divots/line up holes/what ever you call the spots that orient the light to make them fit nice and tight. Been one of the best upgrades we have done.
