Latest LED technology enables the conversion of your factory Xenon/HID bulbs to LED. Xenon bulbs were once recognised as the pinnacle of lighting performance with most car manufacturers offering them as an expensive option, or only available in the higher spec models. Xenon bulbs have been installed in cars for decades but have been slowly phased out, replaced by LED's. Previously, cars with factory installed Xenons could not simply install LED's due to the different wiring looms, ballasts and voltages. This is where it all changes. Spectr EVISION-X LED bulbs are a direct, plug & play replacement for Xenon bulbs. Our bulbs plug directly into the Xenon ballast. No modifications required, no errors, no external ballasts.
