If your rear lights are not working, it means other drivers may not see you properly at night or when braking. Rear lights include tail lights, brake lights, and sometimes rear fog lights. Faults can range from a simple blown bulb to wiring or switch issues. An inspection will determine the cause and restore safe lighting operation.

What does it mean if the rear lights are not working?

This usually means there is a problem with the bulbs, fuses, wiring, or light switch. If both lights are out, it often points to an electrical fault rather than just a single bulb.

Common causes of rear light failure

• Blown bulbs
• Blown fuse or faulty relay
• Faulty brake light or headlight switch
• Damaged or corroded wiring/connectors
• Faulty rear light assembly

Why do you need to fix this problem quickly?

Rear lights are a key safety feature, ensuring your car is visible to other drivers. Without them, the risk of rear-end accidents increases, especially in low-light conditions or poor weather.

How do you know when to get it checked?

You should book an inspection if:

• One or both rear lights do not come on when driving at night
• Brake lights do not illuminate when pressing the pedal
• The rear light warning appears on your dashboard
• Lights flicker or work intermittently
• You notice other drivers signalling that your lights are out

What happens during an assessment?

A mechanic will:

1. Check the rear light bulbs for failure
2. Inspect the fuse, relay, and wiring for faults
3. Test the brake light switch and headlight switch
4. Check the light assembly for damage or corrosion
5. Replace faulty parts and test the system

How much does it cost to fix?

Bulb replacement typically costs $30–$80. Fuse or relay replacement may cost $80–$150. Wiring or switch repairs can range from $150–$500+ depending on complexity.

Is it unsafe to drive with faulty rear lights?

Yes. Driving without working rear lights makes your vehicle nearly invisible from behind in dark or rainy conditions, creating a high risk of collision. The problem should be fixed immediately.
