So my driver side headlight went out on my 02 TL. I replaced the ballast and the headlight and it worked fine, until i turned off the light switch. Once i tried to turn it back on, both lights went stopped working. I kept clicking it on and off, and then 2 headlights start taking turns going on and off. For example, I click the switch on and the left light goes on with the right light off. I click the switch off and on again and then right light goes on with the left light off. So now I usually have to wait like 10 min before I can turn the switch on again for both lights to go on. Any ideas as to what is causing this?
