What can fail
When headlamps and fog lamps run together, high electrical current may overheat the headlamp switch's internal circuit breaker, causing it to open. This makes headlights flicker or blink briefly, and repeated overheating can cause longer outages.
What the fix does
Install a redesigned headlamp switch with an improved circuit breaker and update the wiring harness connector if necessary.
