I have an 01 330Ci and the dash warniing light (light out) is on/off intermittently - both rear lights show up. Seems to be assicociated as much with humidity as anything. My bulb boards and plug thereto all look good - no evidence of deterioration due to excess amperage etc on either male or femaile side. I nonetheless ran a ground wire directly from battery ground to the ground-circuit on both boards (L and R) , but to no vail. Inhdicatgor light still on / off unpredictably. Any suggestions would be appreciated.
