Question about 1990 Geo Prizm
The brake lights work ok during daylight but when the head lights and tail lights are on the brake lights fail.
I had the same problem, what I did to fix it was as follows:

Possibly loose grounding on the taillight assembly. Most taillights operate with dual filament bulb (3 terminal). The metal body of the bulb bottom is usually connected to the body ground. The correct procedure would be to trace the wiring harness from the taillight and determine which is the ground and verify that the contacts are clean and free of corrosion. An alternative is to add a grounding wire from said metal body of the taillight bulb and attached to any bare metal/chassis/body in the rear.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
