    Yeah you didn't use one of these plug and play jobs that use the ballast, did you?

    I'm beginning to believe that if your ballast goes bad 12 volt still passes through it or something along those lines . I put the one wires on a car the other day and 1 side was out bulb worked on other side . Applied d4s conversion bulbs both sides like new ...weird
