I have a 01 g2 430 and when i have the light switch on auto during the day the day time running lights work, when night hits and the headlights turn on the two lights in the middle dont work, but when i switch the lights off the dat time running lights work but when i turn the headlights on they go off.... do i have to replace all the lights because of that? pardon me new to the car game and maintenance .

 

No, you just have to replace the wedge bulbs. When the headlights are on the wedge bulbs come on in the inner lights. When the lights are off the DRL's come on in the inner lights.
