Swift’s Headlights Not Working? Troubleshooting Guide for Quick Fixes
Have your Swift’s headlights stopped working suddenly while driving through Lucknow’s bustling roads at night? This is not only inconvenient but also dangerous. Many Swift owners face this issue due to simple electrical, fuse, or bulb-related faults that can be resolved quickly if identified correctly.
This detailed guide from Beekay, Lucknow’s leading distributor of genuine Maruti Suzuki parts and accessories – Building Trust and Delivering Quality for Over Three Decades – will walk you through stepwise checks and quick fixes to get your headlights back on safely.
1. Check the Bulbs First – Are They Burnt Out?
Headlight bulbs in the Swift have a limited lifespan. If your low beam or high beam is not working:
-
Locate the headlight bulb: Open the engine hood, disconnect the coupler (1), remove the sealing rubber (2), and unhook the retaining spring (3). Then remove the bulb .
-
Inspect for burn marks or broken filaments inside the bulb glass. Replace if damaged. Remember to use a cloth while handling bulbs to avoid oil contamination which can lead to overheating and bursting.
Real life note: Many owners in Lucknow complain about frequent bulb fusing during monsoons due to moisture ingress if sealing rubber is not properly fitted after replacement.
2. Fuse Check – The Often Overlooked Culprit
If both headlights stop working simultaneously, suspect a blown fuse:
-
Locate the fuse box as detailed in your owner’s manual.
-
Replace only with a fuse of the same amperage. Never substitute with foil or wire as it risks an electrical fire .
Warning: If the new fuse blows quickly, there could be an underlying electrical fault. Visit a trained electrician or Maruti-authorised technician.
3. Inspect the Headlight Switch Operation
Sometimes, it’s not the bulbs or fuses but the switch itself:
-
Move the headlight lever between high and low beams.
-
If the high beam indicator light on your dashboard does not illuminate when switched on, there may be a switch circuit issue .
4. Wiring and Connector Issues – Common in Older Swift Models
In older Swifts, especially those used extensively in city traffic:
-
Check for loose or corroded connectors around the bulb socket.
-
Moisture and dust can cause corrosion leading to intermittent or no headlight operation.
Beekay recommends using Maruti Genuine couplers or wiring kits for replacements as “MSGPA Hai To Safe Hai”.
5. Battery Health – Low Voltage Can Cause Dim or Non-Functional Lights
If you notice:
-
Dim headlights while starting or idling, or
-
Both lights go out with a clicking sound when turning on,
It could indicate weak battery voltage or poor terminal contacts. Clean the battery terminals and ensure they are tight. If the issue persists, get the battery voltage checked. A battery nearing end of life can affect lighting performance drastically .
6. Headlight Adjustment or Leveling Malfunction
Swift comes with a headlight leveling switch to adjust beam height depending on load. If your headlights appear dim despite working:
-
Ensure the leveling dial is not accidentally turned to the lowest setting.
-
Refer to load-wise leveling positions in the manual for optimum lighting while driving in city or highway conditions .
7. When Should You Seek Professional Help?
If you have:
-
Replaced fuses and bulbs but headlights still don’t work.
-
Noticed burnt plastic smell near headlight wiring.
-
Repeated fuse blows indicating short circuits.
