While driving home in the dark last night in my 1988 ss I noticed the blinkers didn't work with the lights on. I checked this morning and the work but if I turn on the lights or hit the brakes they don't. I did just change one of the front bulbs a couple of days ago that wasn't blinking. Any help is appreciated. Thanks Guys

 

Double check the bulb you installed, I know from friends/drivers past experience that wrong bulb will cause issues.
