1990 olds 98,

Asked by Oct 20, 2018 at 08:42 AM about the 1990 Oldsmobile Ninety-Eight 4 Dr Regency Brougham Sedan

Question type: Maintenance & Repair

Tail lights come on, right rear brake light and turn signal don't? Turn signals don't work, but solid light comes on in instrument panel.. Bulbs on both sides were replaced. Any ideas?

If your brake lights and turn signals use the same bulb, you might have a defective socket, bad hot wire of broken ground.

Yes. Rear tail light, brake and turn signal are the same bulb. Question if the socket is bad, would the tail light come on? Don't know what a hot wire or broken ground are.....very little repair experience....but same question, if it is either or both.....would the tail light still come on? Thanks.


Sockets have contacts for each bulb segment, so one filament in bulb can work while others don't. Hot wire is to the fuse and ground wire is to the frame.

Thank you. On the way home, the Twilight Sensor for the lights went out I guess....as everything wne t out except the headlamps.....which will not go off....Car was turned off...was able to regain the lights e.g. dash, tail, brake..and signal (but they don't flicker)...by turning the Twilight Sensor off..but the headlamps won't go off. I had to disconnect the battery to turn them off. In light of this new issue....any idea? Thanks again..
