Front Fog Light Indicator
What it means
Shown as a lamp facing left with downward-slanted lines crossed by a wavy line, green in color, this light means the front fog lights are on. It is an information light, not a warning, and differs from the amber rear fog indicator, whose lines point right. If the indicator is on but a fog light does not work, the bulb, fuse or relay is the usual cause.
Symptoms4
- Green indicator on when the fog lights are switched on.
- Indicator on but one or both fog lights are out.
- Fog lights only work with the headlights on, on some cars.
- Moisture or water inside a fog light lens.
Possible causes5
- Fog lights switched on at the light switch, which is normal.
- Burned-out fog light bulb.
- Blown fog light fuse or failed fog light relay.
- Corroded connector from water and dust, as the lamps sit low.
- Light switch or body control module fault (less common).
How to diagnose5
- Check the owner manual: some cars only allow fog lights with parking lights or low beams on.
- Look at the front of the car to see which lamp is out.
- Check the fog light fuse using the diagram on the fuse box cover.
- Inspect the connector behind the lamp for corrosion or water.
- At the workshop: check for voltage at the lamp and test the relay and switch.
How to fix5
- Switch fog lights off when visibility improves to avoid dazzling others.
- Replace the burned-out bulb with the same type and wattage.
- Replace the blown fuse or failed relay.
- Clean or repair the connector, and replace the lamp unit if water got in.
- Repair the switch or wiring, then confirm both lamps work.

Frequently asked questions
When should I use front fog lights?
In thick fog, dust or heavy rain when visibility is low. Switch them off in clear weather, as they can dazzle other drivers.
What is the difference between the green and amber fog indicators?
Green, with lines pointing left, is the front fog light. Amber, with lines pointing right, is the rear fog light, which is much brighter and only for very poor visibility.
