D2S to D1S Base Adapter
Flashtech D2s to D1s Conversion module is a socket containing the igniter for HID Xenon D2 (D2S or D2R) in a housing 100% identical to a D1 bulb socket footprint. The conversion is reversible, which allows this module to be used repeatedly. To convert a D2 bulb to a D1 bulb, simply insert the D2 into the Flashtech socket, press down, turn to the left until it locks. Now it is possible to use any D2 bulb on the market in a D1 system without having to do any major modifications!
