I was driving my '79 Catalina home tonight and noticed both of my headlights went out, luckily I was on an urban stretch of highway with streetlights, so I got off and drove home through town. To see if anything worked, I turned my high-beams on and the driver's high beam came on like normal, so I drove home on the bright light.
I got home and started looking at what I can see with a flashlight, and when I flip the bright lights on, the two low beams and one high beam come on, but when I flip the lever back to low beams, only the running lights are on. What would cause that?
Normally I would suspect a relay went bad, but given the age of the car, I'm not sure if it even has a relay.
I would say change the low beam bulbs first they can often burn out those old cars are kind of funky it's not that it could easily be the high beam low beam switch send me a part of the high beam but not the low beam
Scotty may not see this again, but here are pictures. The only difference between the two is the bright lights switch on the turn signal lever is on in the image on the right. The image on the left is with the normal headlights switch on. Before this happened, turning on the brights would shut off the low beams and turn on the single functioning high beam.
The passenger side bright is bad, a light lead is corroded into the socket and needs replaced.
