sourced a pair of x-treme vision h4 from UK a week back. to be honest, i thought they would provide whiter light - a misconception. anyway, they are great, in terms of focus and the amount of light produced. In my opinion, if either of you guys wants more light while baring the yellow beam, these bulbs are a perfect choice. I have removed them from my honda city12, and now planning on getting an alternative, since i want whitish light for styling purpose. Any suggestions? P.S If any one wants my pair of xvision, PM me. Thank you. =)
