Vision X Superwhite Halogen: H4 (90/100W / HI-LOW)(Set)
VisionX Halogen Bulbs: Over time headlight bulbs dim, long before they burn out. Vision X provides three lines of headlight replacement bulbs to best suit your needs. Our bulbs are superwhite, not the standard orangy-yellow color, for a more natural light color that increases visibility, provides for better depth perception, and reduces eye fatigue. We offer bulbs for not only automotive, but also for bikes, ATV/UTV, and snow mobiles. DH Series are DOT Approved: The D Series line features a B1 coating to provide a superwhite light while still being fully DOT approved. This line features automotive bulbs that will shine brighter and further down the road than standard bulbs.
