It sounds like you are talking about the headlights. Is this correct?
If you ARE talking about the headlights, I would suspect the circuit breaker for the headlights is opening and re-setting. Vehicle headlight circuits are usually protected by an automatically re-setting circuit breaker. This circuit breaker is often located in the vicinity of the fuse panel.
If this is the case, most likely your problem is NOT with the circuit breaker. You probably have either a faulty headlight unit, or worn/faulty wiring to the headlights. Something is overloading the headlight circuit, but not enough to cause the circuit breaker to trip immediately. The overload requires some time before the circuit breaker gets hot enough to trip.
Troubleshooting this problem will be difficult, since it's not a straight short to ground. Get an electrical meter and follow the wiring. You should find your problem.
If it were me, and if I could afford it, I'd hire someone to find and fix this problem.
Best of luck,
