My car has high mount 3rd brake light. With 5 bulbs. And all were burnt out. Is it odd for all the bulbs to be burnt? Vs 1 or 2?
How do you know they all burned out at the same time?
Many years ago we remodeled a bathroom and installed one of those light fixtures that has 4 bulbs in a row. I installed all new bulbs and they all burned out within a year of one another. Seems normal to me.
Depending on the vehicle, if the they’re LED bulbs and integrated into circuit board, when one fails they all fail, which would require replacing the entire assembly.
