Brake Light problems of the 2005 Chrysler Pt Cruiser

It was discovered that the rear lights were not on with the headlights and the brake lights(same bulbs) were not working. Upon investigation, both light bulbs had burst. When taking it to the parts store, they felt that the bulbs had broken because water had gotten into the housing with the bulbs. The housing was not cracked, so it was not due to an accident. And the bulbs on both sides had failed similarly which would indicate a common cause which would seem to be a design defect. This could have easily resulted in a serious accident. Thanks to a stranger, I was informed about it before an accident occurred.

Both brake lights failed at same time. This is the third time. Bulbs receive major damage. Major chance for rear end collision when bulbs blow. Any other reports of this type? this is a big safety issue.
