I'm replacing very often the rear burned light (usually parking light), somebudy know what is causing this ? The alternator charge at 14.2 v could be the cause?
What type light/bulb is it? Is there vibration? Is the bulb bursting from getting wet? Need more info.
Regular bulb(not led), everything is ok, wire is taped, rubber frame is good. I'm thinking install led light and see what happen.
rought roads make bulbs go bad. Switching to LED is possible, but you have to disable failure diiagnostic with Volvo software
