I just replaced the headlight bulb, in my Vectrix, with a HID (Xenon) unit. The difference is absolutely amazing. Now I can really see the road and way far out down the road. Night rides on my wooded area roads are not scary anymore. I chose the 4300 deg. Kelvin bulb. It produces a very bright white light. No blue tint at all. This HID is a Bi-Xenon which provides both main beam and high beam. It has a solenoid activated metal shield surrounding the bulb which blocks part of the light for main beam operation. I had to modify the bulb base of the HID as the OEM bulb base is different from an H4. I also had to install a 7ah 12v SLA battery in the storage to power the HID. The HID draws up to 15 amp during ignition ( about .5 sec.) then stabilizes at 3.5 amp. I had no wiring schematic to see if there is a source wire, behind the headlight, that would power the HID. This kit plugged into the OEM headlight connector to run relays for the high/low function. I will just have to charge the V batteries and my HID battery at the same time. The only bug is that the headlight on light flashes indicating the headlight is out. The high beam indicator light also flashes when using high beam. I tried connecting various resistors at the headlight plug to fix this with no success. A piece of electric tape can remedy this (how un-technical) .
