1000's of people have no idea that there vehicles rear brake light are not actually on..because when they step on the brakes! The brake light come on,Running lights are the lights orange lights in front next to the headlights and the rear running lights are the red lights that stay on when u are driving!! The brake lights are in the same tail light fixture!! So for what ever reason people's running lights are usually a bad ground!! Maybe a bad bulb? 1 bulb could have went out so the other bulb in the other tail light fixture won't work? The most vehicles that I see with NO RUNNING LIGHTS ARE THE NEWER VEHICLES!! And people are driving fast and in the complete dark sometimes..The head lights don't work neither...Due to the running lights not working!! And people will never NO that the taillights running lights do not work unless someone brings it to there attention! Or they get rear ended or killed by stopping and nit realizing that they had/have no running lights!! I drive 2. Hrs a day xommuting TO & FROM WORK!! I SEE ABOUT 3-6 vehicles or more with people with NO HEADLIGHTS OR RUNNING LIGHTS THAT DONT WORK!! SO THE VEHICLE ISNT SEEN BY MOST MOTORISTS!!
