Not worth the money.
I purchased these in a H1 style for my 01' Ford Excursion which has aftermarket Spyder headlights. One of the original bulbs failed so I figured I would splurge and give the PIAAs a try, figuring for $80 they must be impressive. Not so much! While they are a whiter light, they are not noticeably brighter. For all the hype and big price tag, these bulbs fell way short in my opinion. Worse yet, I bought a set of H4 PIAAS for my 15' SKIDOO, yet to be installed. Hope they are better than the H1's.
