Where is the circuit breaker for headlights a 1981 Oldsmobile Cutlass Supreme?

The 1981 Oldsmobile Cutlass Supreme doesn't have a dedicated circuit breaker *just* for the headlights. Instead, the headlight circuit is protected by a fuse in the fuse box (often under the hood, but sometimes inside the car, depending on the specific model).

To find the correct fuse, you'll need to consult your owner's manual. It will have a fuse box diagram showing which fuse is for the headlights (it might be labeled "Headlights," "Headlamps," or something similar). If you don't have the manual, you can often find a digital version online by searching for "[Year] Oldsmobile Cutlass Supreme owner's manual".

It's important to note: if the headlights aren't working, it's *more likely* a blown fuse than a problem with a circuit breaker. Circuit breakers are less common in older vehicles like this one for smaller circuits.
