Are they on?

I am really disappointed with the light output and these are not "extremely bright." I have white LED headlights and I thought that the yellow would contrast and fill in side areas not covered by the headlights. All I see are yellow highlights to each side of the headlight beam. Switch them off and there is barely a difference. To be fair I didn't have opportunity to try these in fog. I'm not sure how you rate longevity but these will probably last forever! Not that it makes much difference since they don't really do much, unlike the OEM lights that they replaced before one go them blew. Perhaps I should have bought the white.
