The DRL light on a Honda Civic signals the status of the Daytime Running Lights. It can indicate that the DRLs are active by design, or that the DRL system has detected a fault needing service.
Daytime Running Lights (DRLs) are intended to improve daytime visibility for other drivers. On Civics, DRLs may be part of the headlight assembly or are separate LED strips depending on the trim. The dash DRL icon visible to the driver shows whether the feature is operating normally or if there’s a problem. If the light appears unexpectedly, flickers, or stays lit in a way that doesn’t match the driving mode, it’s wise to inspect bulbs, fuses, and wiring or consult a Honda service technician to diagnose the issue.
What the DRL light indicates
DRL indicators come in two broad meanings: normal operation and a fault in the DRL system. The list below covers common scenarios you might encounter in a Honda Civic.
- DRLs are functioning as designed: The dash may show a DRL indicator when the ignition is on and daytime lights are active. In this case, the lights are simply doing what they’re supposed to do and require no action.
- A fault is detected in the DRL circuit: If the DRL warning symbol appears, it signals a problem with the DRL system that should be inspected by a technician.
- One or more DRL bulbs are burned out or degraded: Especially in models where the DRLs use dedicated bulbs, a failure can trigger a fault signal or cause the DRLs to darken.
- Power, relay, or wiring issues: A fault in the electrical path feeding the DRLs can trigger warning indicators or cause intermittent operation.
- Software or control module considerations: In some Civics, the DRL behavior is controlled by the body control module or a similar computer; software issues or recalls can affect DRL operation.
Regardless of the exact cause, if the DRL light shows a fault rather than simply indicating normal operation, prioritize a check sooner rather than later. A faulty DRL system can reduce daytime visibility for other drivers, which is a safety concern.
How to respond if the DRL light indicates a fault
The following steps can help you diagnose common DRL issues. If you’re not comfortable performing these checks yourself, arrange a visit with a Honda dealer or qualified mechanic.
- Visually inspect the DRL bulbs: Look for burned-out or cloudy bulbs, especially if the DRLs are not illuminating on one side or at all.
- Check the DRL fuses: Locate the fuse box and verify that the fuse labeled for DRLs or lighting is intact and not blown.
- Inspect related wiring and connectors: Look for loose or corroded connectors in the headlight/DRL circuits and repair if needed.
- Test the DRL relay and control module: A faulty relay or control module can cause intermittent or no DRL operation; testing or replacement may be required.
- Consider software/service bulletins: Some DRL issues may be addressed by a software update or recall; check with a Honda dealer for any applicable campaigns.
Before starting, read your owner’s manual for model-specific guidance on DRL icons and fuse locations. The steps below provide a general approach.
If the issue persists after these checks, schedule a diagnostic with a Honda service center. DRLs are a safety feature, and unresolved faults should not be ignored.
Is it safe to drive with a DRL fault?
Driving with a DRL fault isn’t typically illegal, but it reduces daytime visibility for other drivers. If your DRLs aren’t functioning and the warning stays active, have the system inspected promptly to restore full visibility and ensure all lighting operates correctly.
Summary
In a Honda Civic, a DRL light on the dashboard communicates the status of the Daytime Running Lights. It can simply indicate normal DRL operation, or it can alert you to a fault in the DRL system. If the warning appears, check bulbs, fuses, and wiring, and seek professional service if the problem isn’t easily resolved. Regular maintenance and staying aware of DRL status helps keep daytime visibility at its best.
For model-specific details, consult the owner’s manual or contact a Honda service center, as DRL configurations can vary by year and trim. Regular checks during routine maintenance can prevent DRL-related issues from going unnoticed.
What is the cost of replacing DRL lights?
Daytime running lights automatically turn on when you start the engine. It works by relying on sensors to detect ambient daylight. DRL costs between $20 and $80 to install daytime running lights.
Do DRLs drain my car battery?
Daytime running lights are only illuminated whenever the engine is running. Since they're turned on and off automatically, there's no risk of forgetting to turn them off and drain the battery. DRLs also require very low power, so they'll have little to no impact on your car's battery life.
Is it okay to Drive with the DRL light on?
No, as they do not produce enough light to illuminate the road at night-time. DRL's are only suitable for daylight hours and when in use, your lights to the rear and instrument lights may not be on in some cases so it is extremely important to remember that headlights still need to be switched on before darkness.
Why is my DRL light on in my Honda?
Visibility during daylight driving hours unlike headlights. DRLs don't help you see the road they help others see you you know to keep your safety in low light conditions.
