When it rains the tail lights fill up with water and the lights do not work correctly. And sometimes they do not work at all. It holds water and the lights flash in a christmas tree light manner. Also when the breaks are stepped on the blinkers do not work. Also when you step on the break the blinker indicators on the instrument panel remain lit up green. I have replace bulbs as well as the whole light housing. Even drilled wholes in the bottom of the light housing units so the water can drained. Nothing can remedy this problem it is very dangerous.
