Ok. On my 2016 prime my taillights went out. My brake lights work, but not my taillights. I went to check my bulbs and found out my car has partial led’s. I don’t understand why brake lights work and taillights don’t not like standard bulb with two filaments. Any suggestions appreciated. I have an appointment with Mercedes Benz dealer next Thursday. Using rear fog lamps as taillights for now. Would like it to be an ez fix I can do myself e.g. fuse. Holler. Thanks.
