I've never heard of an H1 bulb before, but check this out. I'd check into seeing if theres some type of "trick mod" like the 9005 into the low beam socket for these H1 bulbs. Do you know what the wattage is on them? I don't think you'll be unhappy with the PIAAs, they make a quality product, period
Just for the record, I did the 9005 into the low beam socket on my CSVT, before I got the MM quads w/ HIDs and it made a HUGE improvement. I also just did the 9005 into the low beam in my Regal and it really made a difference, even though the lights arent' clear, they have those vertical lines in them from the factory and it still made a BIG difference
Let us see some pics when you do the bulbs, whatever they are
