The question of how long a blinker (turn signal) stays on high isn't straightforward. It doesn't have a fixed duration like a traffic light. Instead, the duration is determined by a few key factors, and malfunctions can significantly alter its behavior. Let's delve into the specifics.
What Determines Blinker High Duration?
The duration of a blinking turn signal isn't about a "high" setting; it's about the signal's consistent operation. Ideally, it should blink at a regular, legally mandated rate. This rate is usually specified by your vehicle's manufacturer and varies slightly between models. However, several things influence this seemingly simple function:
-
The Hazard Lights (Emergency Flashers): When you activate your hazard lights, both front and rear indicators flash simultaneously, usually at a faster rate than the regular turn signals. They'll remain on until you manually switch them off. This isn't a "high" setting; it's a separate system designed for emergency signaling.
-
Bulb Condition: A burnt-out bulb in your turn signal circuit will affect the blinking rate. Sometimes, it will cause the blinking to become noticeably faster or even erratic. This is because the system is designed to detect such issues; a faster blink is a visual warning that a bulb needs replacing.
-
Electrical System Issues: Problems within your vehicle's electrical system, such as low battery voltage or a faulty turn signal switch, can lead to irregular blinking or non-functioning signals. These issues may cause the blinkers to flash slower than normal or even fail entirely.
Why is My Blinker Flashing Too Fast or Too Slow?
As mentioned, an irregular blinking rate is often a warning sign.
Faster than Usual Blinking:
A faster blink rate typically indicates a burnt-out bulb. The system detects the reduced load and increases the frequency. Check all of your turn signal bulbs (front and rear) and replace any that are malfunctioning.
Slower than Usual Blinking:
Slower blinking often points to a problem within the electrical system. This could be due to low battery voltage, a faulty turn signal switch, or issues with the related wiring or relay. It may require a professional inspection and repair.
How Can I Tell if My Blinker is Working Correctly?
The most effective way to check is by manually testing them. Turn on your turn signals (left and right) and observe the front and rear indicators. They should blink at a consistent rate, and all bulbs should be illuminated. If you observe any inconsistencies, inspect the bulbs and consider a professional inspection if the problem persists.
What if My Blinker Doesn't Work at All?
If your blinkers fail to activate, it's a more serious issue than a simple blinking rate problem. This points to a malfunction in the electrical system—possibly a blown fuse, a faulty switch, or a more significant electrical problem. It's crucial to get this resolved promptly for safety reasons.
Conclusion: It's Not About "High," It's About Consistency
There's no "high" setting for your blinker duration. The consistent and appropriate rate is crucial for safe driving. Irregular flashing is almost always a sign that something needs attention, be it a burnt-out bulb or a more involved electrical issue. Regular checks and prompt attention to any unusual blinking patterns can prevent potential accidents and ensure road safety.
