I Removed The Ds2 Bulbs From My Pre F/l Vectra A While Ago ,to Find It Came With 2 Different Bulbs

This Is What Was Writen On Them

2)osram Xenarc Ds2 35w 66040 Germany 5138 754442 03x Dot Q2q4


While I Had The Bumper Off My Atsra Today (changing Grills) I Decided Id Change The Side Lights Bulbs For Mtec (as I Had These In My Vec With The Xenons And The Look A More White)
