If your turn signal or indicator light is not working, it reduces your ability to safely communicate with other drivers on the road. This can be caused by a blown bulb, faulty relay, wiring issue, or switch failure. Since functioning indicators are a legal requirement and essential for road safety, the issue should be addressed quickly.

What does it mean if your turn signal is not working?

When the indicator light does not flash, it usually means the circuit has been interrupted. This could be a simple bulb failure or a deeper issue with the flasher relay, wiring, or switch.

Common causes of turn signal or indicator light failure

• Blown or burnt-out indicator bulb
• Faulty turn signal relay or flasher unit
• Wiring or connector problems
• Broken turn signal switch on the steering column
• Blown fuse in the lighting circuit

Why do you need to fix this problem quickly?

Driving without functioning indicators is unsafe and illegal. It increases the risk of accidents by not signalling your intentions to other drivers. Immediate repair is needed to maintain both safety and compliance with road regulations.

How do you know when to get it checked?

You should book an inspection if:

• One or both turn signal lights do not flash
• The turn signal flashes too quickly or too slowly
• The dashboard indicator light doesn’t work
• You hear no clicking sound when the indicator is on

What happens during an assessment?

A mechanic will:

1. Inspect the indicator bulbs and replace if faulty
2. Check fuses, relays, and the flasher unit
3. Inspect the wiring and connectors for damage
4. Test the turn signal switch for proper function
5. Confirm correct operation of all indicator lights

How much does it cost to fix?

Repair costs vary depending on the cause. Bulb replacements typically cost $50–$120. Relay or fuse repairs may cost $120–$250. If the switch or wiring needs replacement, costs can range from $300–$600+.

Is it unsafe to drive with faulty turn signals?

Yes. Indicators are critical for safe driving, allowing you to signal lane changes and turns. Driving without working turn signals is unsafe and may result in fines or failed WOF/inspection. The issue should be repaired immediately.
