Swift’s Headlights Not Working? Troubleshooting Guide for Quick Fixes
When your Maruti Swift’s headlights suddenly stop working, it’s not just frustrating—it’s dangerous. Whether you’re driving through the busy streets of Lucknow at night or navigating foggy mornings, functioning headlights are crucial for your safety. But before you rush to a mechanic, know this: many headlight issues are fixable at home with a bit of guidance.
In this article, we’ll walk you through the best and most common headlight issues in the Swift, and how you can troubleshoot them confidently using your vehicle’s systems. With genuine products available through Beekay Group—Lucknow’s leading distributor of Maruti parts—you can be assured of quality every step of the way.
1. Start With the Basics: Check the Headlight Switch
One of the first things to inspect is the lighting control lever located on the steering column. Sometimes, it may simply be in the wrong position.
-
Ensure the lever is turned fully to the headlight icon.
-
For models with an automatic lighting system, check if the sensor is obstructed.
-
Inspect the headlight leveling switch (if equipped) to make sure it’s not dialed to the lowest level, reducing beam visibility.
This step seems basic but is often overlooked. According to the manual, lighting system operations are part of standard electrical checks during routine inspections (Page 5, Section 8: Electrical).
2. Inspect the Fuses: A Common Culprit
Blown fuses are a leading reason for headlight failure. Your Swift is equipped with a fuse box located under the dashboard and another in the engine compartment.
-
Find the fuse marked for the “headlight” or “lamp” function.
-
Replace any blown fuses with genuine MGP fuses for safety and longevity.
Using non-genuine fuses can affect the overall system’s performance and may void warranty coverage. Beekay Group offers only authentic Maruti Genuine Parts (MGP), ensuring compatibility and reliability.
3. Battery Health Check
Your Swift’s lighting system is powered directly by the battery, so if the headlights are dim or not turning on at all, check:
-
Battery voltage using a multimeter (should be 12.6V+ when fully charged).
-
Terminal corrosion or looseness.
-
Signs of leakage or low electrolyte levels (Page 5, Section 8: Electrical – Battery Electrolyte).
If the battery is underperforming, it may affect multiple electrical systems, not just the headlights.
4. Check the Headlight Bulbs Themselves
Bulbs have a limited lifespan and can burn out suddenly or progressively dim over time.
-
Carefully remove the bulb casing and inspect the filament.
-
Replace any burnt-out bulbs with MGP-approved halogen or LED bulbs, depending on your variant.
-
Avoid touching new bulbs with bare hands, as oils from your skin can shorten their lifespan.
Bulbs are classified under normal wear and tear items, so they are not covered under the standard warranty (Page 5, Section 0-35: Warranty Policy).
5. Look at the Wiring and Connectors
Loose or corroded connectors can cause intermittent or complete failure of headlight operation. Swift’s wiring harness connections are checked during service for looseness (Page 5, Section 8: Electrical – Wiring Harness Connections).
Check for:
-
Damaged wires near the headlight assembly.
-
Moisture or rust inside connectors.
-
Frayed insulation.
If you’re unsure about doing this yourself, ask your local mechanic to inspect it. You can source OEM wiring harnesses through Beekay outlets across Lucknow.
6. Test the Headlight Relay
Relays regulate the electrical current that flows to the headlights. If they malfunction, your headlights might not activate even if everything else is in order.
-
Locate the relay box (under the hood).
-
Listen for a click when switching on the lights—no sound could indicate a faulty relay.
-
Relays should be replaced with exact MGP matches to ensure proper electrical flow.
Relays are also considered part of the lighting system/horn operation checks as listed in the periodic maintenance schedule (Page 5, Section 8: Electrical).
7. Consider the Multifunction Switch Failure
If both low and high beams fail and the bulbs and fuses are fine, the issue could lie with the multifunction switch—the lever used to activate the lights.
-
This can wear out due to frequent use.
-
It’s a more complex replacement that may require a technician.
-
Beekay can help you get the exact switch model for your Swift variant.
8. When All Else Fails: Consult with Experts
If none of the above solutions restore your headlights, the issue could stem from a deeper electrical fault, possibly involving the Electronic Control Module (ECM)—especially in newer Swift variants.
