H4 Plasma Ion Yellow Twin Pack Halogen Bulbs


Headlight Bulb Replacement Guide




Plasma Ion coating transforms white light into amber light without diminishing the strength of the beam. Plasma Ion technology allows more than 97% of the light produced by the bulb to pass through, compared to as little as 65% through dyed glass. The long wavelength Plasma Ion beam reduces reflective glare for dramatically increased visibility in snow, rain, and fog.
