1978 Ford Thunderbird stop lights

You could try crying lol. Just kiding. If you have a test light see if there is power at the rear light. If not go to the switch it is on the brake pedal and see if the switch is getting power, one wire will be hot and the oter wires will go to turn sig and cruise control. Then depress pedal and see if power goes thru the switch. If it doesn't then the switch is bad, if it does then the turn signal switch is bad if you ar not getting power to the rear lights. One other thing if you pull the floor carpet up behind the front seat, one wil be the brake light/turn signal. Poke that with a test light and see if it works. If itdoes there then you have a broken wier someplace.
