At times when driving with headlights on the driverside taillight will go out and will cause the middle and passenger brake light to stay on. If I turn the headlights off the middle and passenger taillights work only when pressing the brake peddle. I have removed the tail light and checked it for being burned out, corrosion or being loose and it is fine. I put the bulb back in and the drivers side taillight works fine and the brake lights work as normal. This happened a second time and I checked the bulb. Again nothing was wrong with it. I changed the bulb with a new one. This is actually the second new bulb in that socket. This happens while driving or standing still while headlights and tail lights are on. This started happening in December 2020. It is worrisome as you are driving with no brake lights working if you have your headlights on when it rains during the day or while driving at night and the only way you will know it's happening is if you happen to get out of your car while the headlights are turned on.
