Rear Fog Lamp Indicator Light

The Bulb Check: Rear Fog Lamp Indicator Light
Some vehicles have rear fog lights in which case there is an indicator light on your dashboard to alert you that they are on. Vehicles can sometimes have two fog lamp indicator lights. Don't confuse this one for the fog lamp indicator for the front fog lamps.
The rear indicator will typically be amber or orange and will be pointed to the right, whereas the front fog lamp indicator is usually green and points to the left. Be sure to always check for this indicator as it can blind people behind you if you have them on driving down the road. Plus prolong use of fog lamps will burn them out sooner than other bulbs as they were not designed to run as long as headlamps.
