Why are my headlights flickering on and off?
A bad headlight switch or relay could also be to blame. The headlight switch assembly on older vehicles includes a built-in circuit breaker, and when a short circuit occurs, it can cause the headlights to flicker. This is why flickering headlights used to be common with older models.
