Just trying to find out which bulb gets a better use. It looks like the H1 bulb is a tad bit smaller than the H3, but i don't know if that's a factor. the reason i'm asking is because they are making projectors that take either h1 or h3 bulbs for the 4th gen accords. I’ve heard that the projectors suck for the 4th gen accords, but my question is in regards to the bulb itself. any info would be appreciated. thanks.
