I also installed brighter Sylvania Ultras in my highs but these appeared to suck big time compared to the HID's.
Frankly I could not see any difference really between the Ultra's and the OEM bulbs. I think I was ripped off with these bulbs on eBay. This would be the first time I was screwed so I guess I'm lucky.
I may not have noticed but by a stupid mistake I took out one OEM bulb and later put it back in, not knowing I compared the brightness of the Ultras and the HID's. Both Ultras looked more or less the same but dim and yellow against the HID's. Later I noticed that the two bulbs on the bench were an OEM and a new 'Ultra'.
I may get real Ultras or put HID's in the highs and suffer the slow warm up. The odd thing is the real Ultras are more expensive than many HID's with reasonable shipping charges, go figure.
Thanks! I got ultra bright hallogens - is that wat you mean? They were a bit better but still not great. I've just got HIDs for the low beam so far simply because the kit was quite expensive because I had to get one that had a 'starter' in it (something to do with the car being far too clever and knowing that a bulb is out and a warning light...) but I may get them for the high beam too in time. I also indulged my inner chav and got some LED daytime running light strips like the new Audis have. I hope they look ok. I'll put a photo up when they're fitted.
