Default Headlights blink on and off

I have a stock 1991 Mustang GT Convertable. I replaced the fog lights with OEM lights. After the the fog lights have been on for a few minutes all the lights start to blink and then they all turn off. This only happens when the fog lights are on. I need any help I can get. Thanks

Yup, common problem. You need to install a relay to run the fog lights. One of the mustang magazines did an article on it years ago but I don't remember which one. It was called "Death to Blinky"


Here ya go...
