ok fuse and bulbs are ok then you have to start looking at switches there is a switch on the arm of the brake pedal, use a test light and make sure 12 volts is going through the switch then that voltage goes upto the multifunction switch in the stearing colum, this has your hazard lights, turn signals, and bright headlamp controls in it, check this by turning on the hazard lights see it the tail lights flash this uses the same wire as the brake light so if it lights you have a bad brake switch at the pedal, if nothing lights up 90% chance its the multi function switch
