What is the blue light on my Honda dashboard?
The blue dashboard light on most Honda models is the high-beam indicator.
It appears as a blue icon of a headlamp with rays and signals that the headlights are currently in the high-beam position. Depending on the model and year, this icon may also reflect automatic high-beam functionality, meaning the system is actively managing high and low beams in response to lighting conditions and traffic.
Understanding the blue light
Normal operation
When you switch to high beams, the blue indicator lights up on the instrument cluster to remind you that the headlights are emitting a brighter beam. The icon is typically shaped like a headlamp with several diagonal lines projecting outward. This is a standard cue used across many Honda models to indicate high-beam use.
Automatic high beams
Many newer Honda models offer Automatic High Beam (AHB) or Auto High Beam Assist. In these configurations, the blue indicator may light when the system is actively toggling between high and low beams or when high beams would be used but are suppressed to avoid blinding other drivers. The exact behavior can vary by model and model year.
If the blue light appears even when you believe your headlights are on low, it could be due to a sensor or setting related to the automatic function, or it could indicate a temporary issue with the headlight system. Always refer to your owner’s manual for model-specific behavior.
To quickly verify what you’re seeing, use the following checks.
Before you review the checklist, consider that some Honda models may display other blue indicators for different systems; the high-beam icon described here is the most common.
- Confirm high beams are physically on by engaging the stalk (usually push the lever away from you). If you see the blue icon and the lights are clearly bright, you’re in high-beam mode.
- If you’re using the automatic feature, the icon may appear even when the lights are not in a manual high-beam state, indicating the system is actively managing beams.
- If the icon remains on with low beams or flickers unexpectedly, inspect the windshield area for dirt, frost, or obstructions that could affect the automatic sensor and check if the feature has been manually disabled in the vehicle’s lighting settings.
In short, the blue light most commonly signals high beams are active or that an automatic high-beam system is engaged. If you notice odd behavior, consult the owner’s manual or contact a Honda dealer for model-specific guidance.
What to do if the light behaves oddly
Before taking action, make sure you’re safely parked or stopped in a suitable location when diagnosing the issue. If the blue light stays on or behaves inconsistently, use the following steps.
- Turn off high beams by returning the headlight switch to low beam or by using the stalk to switch off the automatic high-beam function.
- Clean the windshield near the rearview mirror if your model uses a camera-based automatic high-beam system, since dirt or glare can affect sensor performance.
- If your vehicle has Auto High Beam (AHB) and it seems too aggressive or not responsive, try disabling AHB from the lighting settings or the stalk switch (per your model’s instructions) to see if the behavior normalizes.
- If the blue light persists without high beams or you notice dim or flickering headlights, have the system inspected by a Honda service center to check sensors, wiring, fuses, and the headlight assembly.
Unresolved or repeated anomalies should be evaluated by a professional. A malfunctioning high-beam system can affect nighttime visibility and road safety, so timely diagnosis is important.
Summary
For most Honda owners, the blue dash light is the high-beam indicator, signaling that the headlights are in high-beam mode or that an automatic high-beam system is actively managing illumination. Use the headlight stalk to switch between high and low beams and keep sensors and lenses clean if your vehicle has AHB. If the light behaves abnormally, follow the troubleshooting steps above and seek service if necessary to ensure safe nighttime visibility.
What does the little blue light on my dashboard mean?
It indicates that the engine hasn't yet reached its optimal operating temperature, and you should drive conservatively. When the blue light disappears, you can push engine performance to merge onto the highway, begin towing a heavy load, or climb a steep grade.

What is the blue light on my Honda Dash?
A blue engine coolant temperature light only indicates one thing: that your coolant, or antifreeze, is too cold. In fact, the temperature is so low that it is possible for your radiator to get too cold, thus resulting in your engine freezing up and not being able to start.
Can I drive with the blue coolant light?
