Will everybody tell me what they think the difference is between a 9003 and an H4 bulb? Ive looked and looked at these two bulbs side by side and I cant see any difference. Ive tried H4's and I know they fit and work in place of a 9003 so whats the difference.
My one guess is that an h4 can be made at different wattages whereas the 9003 standard says it has to be 55/60 or whatnot.... tell me waht you think
