First time poster, I have a 1994 Ford Ranger 4x4 XLT Ext Cab, 4.0L (if that makes any difference) and the tail lights stopped working, just the part that is supposed to be on when the head lights are on. Both rear turn signals, both back up lights and both brake lights work. The tail lights and brake lights share the same dual filament bulb and neither were burnt out but I changed both anyway; still the same, no tail lights and the brake lights work. Any suggestions for this newbie?
