when the headlights are not running on my vehicle & the brake pedal is depressed both rear brake lights will illuminate - if the headlights are on & you depress the brake pedal only the drivers side rear brake light will illuminate, while the passenger side brake light will go completely out[/quote:51958a7c5b]
