The DSC 30 lamp is a 6V 30W Halogen Lamp that is commonly used for microscopy and is supplied by DSC Optical Services Inc (JC6V30W) [2]. It is also a common part used for BMW 5 series (G30) [1] to reset the DSC control unit. The DSC 30 lamp is known to be the cause of DSC, ABS, and BRAKE lights all coming on simultaneously for the 2001 740i M Sport [3]. It can be replaced with a pre-charge pump from a junkyard, as instructed by Timm, to fix the issue.
