Seriously, seriously impressed with these...

Had been running the "regular" Silverstars until one blew out (after I think 3 years). Hated having to buy two bulbs but decided to take advantage of the situation and upgrade to the ULTRAs. 20% off (online) coupon at Advance Auto meant I got the set for ~$36 OTD.
The chart above claims these are brighter than the regular Silverstars and based on my unscientific observation THEY ARE RIGHT. I just drove 150+ miles in the rain at night and these things were FANTASTIC, noticeably better than the Silverstars. On HIGH BEAM they are UTTERLY INSANE. I am going to have to take some pics on a clear night with no cars on the road but I swear they lit up anything reflective but especially road signs from distances I've never thought possible.
Keep in mind this is on a 1997 Camry with 217k miles and cheapie (non-OEM) lenses. I haven't been this happy with a headlight upgrade for YEARS.
YMMV, this is just one opinion, yadda yadda yadda, but I just had to share. These things ROCK!
