These are my Ultras..... I got them In July, same as the focus, when I discovered one night that I only had one running headlight [rolleyes] they're about a little less than four months old, and I took this picture a couple days ago.... I think they're pretty bright... picked em up for about $40 inc. tax from pepboys (lol)
oh and I don't know if anyone's answered this, but yes, your bulbs do get dimmer with age... usually a couple of years though...
ah now, as you see here......the one light that did work was kinda yellowed out and not so bright..... and the other one, well, was burnt out or something... lol
