A little bulb help. Looks like HB2s are an oddball.

Man, those JCWhitney lenses seem to have few refractory cuts. Maybe it's just the pic. No bulbs with those. Figure about $8 for each H4. Probably less for H1s. Don't know about 9003s. I also wonder if the JCWhitney lens assys have separate high-beam and low-beam lenses since they serve different needs. I mean, if you buy a pair, do you get low-beam lenses only, only high-beams lenses, or one low-beam and one high beam? I would hope the latter. No info that I could see. Should call first, even if ordering online.

I hear those are a nice improvement over run-of-the-mill sealed halogens, but not on par with e-codes in light output and beam control. FWIW, I doubt e-codes will ever be dot-legal...
