My new chevy tail lights blink fast and show a warning that they are out when the blinker is on. Is there a certain resistance needed? 2015 chevy silverado with a utility bed.
If the dealer gives you any grief because a utility bed was installed, not by dealer, take it to where the bed/tool bin was put on, they may have been the ones to mess up some wiring if the lights are part of the service bed ...like this
A good wire and ground is necessary for a light to work, not to mention a bulb that is not burnt out.
