Im interested in changing all the interior lights to a crisp bright white or maybe a touch of blue rather than the factory amber lights. I think this will look particularly good in the ambient overhead light which remains on while driving with the headlights on. Im also having 4 AMG illuminated door sills installed next week.
I contacted the guys at autoilumination.com they "think" the lights are Ba9s minature bayonet + some 39mm festoons. I have no idea what this means or if it is accurate. Does anyone have experience with replacing/upgrading all the interior lamps of a W211?
