:smiley_thumbs_up: OMG! Thanks Stangshcky12....I have taken them and cleaned them several times never suspecting that they had circuits in them...I guess each one has a circuit board, so I shall replace them both!! If it works out I'll let you know so others may benefit from the experience! Also, perhaps this is why they have the rubber rings around each lamp....to prevent water from ingressing to and affecting these circuits....so maybe I will seal the new ones a little better, with a dab of silicone. Do the front headlamps and/or parking /turn signals have their own circuits as well?
