Automatic Headlight Dimmer and Malfunction Indicator Symbols

Automatic Headlight Dimmer

These are all Automatic Headlight Dimmer indicator symbols. The system is also known as the High Beam Assistant. Shown in the traditional blue of the high beam indicator or in green, the symbols indicates that the high beams are on and that the system will automatically (AUTO or A) switch between the low and high headlight beams on the automobile depending on whether or not sensors detect oncoming vehicle head lights in the distance.

• But first, is one of these truly your symbol?? If yes, continue below.
• Otherwise return to our main Picture Symbols page and scan again!

The letter A may or may not be seen inside the drawing representing a lamp. in fact, it often just seems like a game of where else can we drop the letter A! The lines pointing out represent light.

Note that some manufacturers use the light in green until the high beams are automatically turned on the indicator then turns blue.

And believe it or not, similar systems have been available in some form on high-end vehicles since the 1950s!

Combined versions

One manufacturer has chosen to combine the auto high beam indicator with the park light indicator. With the auto high beam system on, the symbol is seen in blue and green. With the high beam system off, the light is shown in white. The park lights are on in either instance.

Black and white or gray scale versions

This version, in gray scale or black and white, indicates that the high beams have been turned off because a light has been detected in front of the vehicle. The high beams will reactivate when the light is no longer detected. The starker black and white indicates the system is on and working. All these symbols would be active if the system were in use in daylight.

Malfunction indicators

These versions are Automatic Headlamp Dimmer Malfunction indicator symbols. They are displayed in yellow/amber/orange. The letter A, for Automatic, sits inside two of the headlamps and an exclamation point is added to the side in one. The other has the word AUTO inside and the color alone is used to indicate a problem. The headlights themselves will continue to function in high or low beam, but they will need to be cycled manually.

Finally, there is this one from Audi which for some reason they use as an Automatic Wiper Fault Indicator as well.  This looks like a hat or a lid open on one side with beams coming out of it to an oval shape in yellow/amber.

All these indicators use the shape of an old style headlamp with lines pointing outward, which are meant to be beams of light. There are others that use these elements, such as those to the right, so don’t confuse them. Click here to learn more.
