I just purchase a 84 318i and cannot figure if the obc light should be bright. I replace the bulbs (computer board)$40.00 from dealer and the little bulb in back of the obc. Still dark. When i turn the parking light on or headlight it does not illiumate at all. Can someone tell me if it should be bright? If so, what do I need to do to get it to shine bright. Thanks,
