I've replaced the OBC lightbulbs for my 89 535i 3 times, and the new ones keep burning out after only 2-3 weeks. The replacements do not look like the old ones that were in the OBC - the new ones have a blue base. My dealer tells me that the blue base bulbs are the correct part, but they burn out so quickly.
Does anyone have a different part number or source for OBC bulbs that will last longer?
Thanks
Mike
