97's use 9003 bulbs, which are functionlly H4 (euro) bulbs. There are tons of high quality high wattage H4 bulbs available (since Europeans are not limited by law to 55/65 watts (and have useful beam patterns). Not to mention, there are high quaility sockets for H4, Patrick is right, the quality on those CL harnesses are pretty bad, not thier fault, it's all there is available for 9007, but there is no excuse for using inferior sockets for a H4.
99's use 9007, a much inferior design. The only high wattage 9007s seem to be Korean POS (no, I don't think that is redundant), I found out even the Hella 80/100 9007 are those same Korean bulbs.
I would gladly trade anyone even up for 97 headlight assemblies for my 99s. I'll take function over looks any day.
(I suspect the reason Subaru made the switch has something to do with wanting those clear (non-fluted) lenses and 9003s didn't do it, or were to expensive)
Danial told me a long time back that there was not much I could do while "saddled with that 9007 crap"
