Low Beam (Dipped Headlight) Indicator
What it means
Shown as a lamp with downward-slanted lines, green in color, this light means the low beam headlights are on. It is an information light, not a warning, and not every car has it; some only light up the instrument panel. If the indicator is on but a headlight does not work, the bulb, fuse or connector is the usual cause.
Symptoms4
- Indicator on when the headlights are switched on or come on automatically at night.
- One headlight does not light or is dim.
- A headlight failure message on the display.
- One headlight flickers or cuts out.
Possible causes6
- Headlights on manually or in auto mode, which is normal.
- Burned-out low beam bulb.
- Blown fuse or failed relay.
- Corroded or heat-melted connector behind the bulb.
- Failed xenon ballast or modern headlight module.
- Faulty light switch or automatic light sensor (less common).
How to diagnose5
- Turn on the headlights facing a wall and check both sides are equally bright.
- Read any message on the display, and check the owner manual for the bulb type.
- Check the fuse using the fuse box diagram.
- Inspect the connector behind the bulb for melting or corrosion.
- At the workshop: test the ballast on xenon lamps, or read lighting module codes.
How to fix5
- Replace the burned-out bulb with the same type; replacing both sides keeps the light even.
- Replace the blown fuse or failed relay.
- Replace a melted connector and repair the wiring.
- Replace the ballast or the complete headlight module on modern systems if confirmed faulty.
- Aim the headlights after the repair and confirm they work.

Frequently asked questions
Should I replace both bulbs if one burns out?
It is usually recommended, since both bulbs are the same age and the other may fail soon; it also keeps the light color and brightness even.
Why does the indicator come on by itself in the daytime?
In auto mode the car turns the lights on in darkness, tunnels or dust. If they come on in bright daylight, the light sensor may be dirty or faulty.
