Hyundai Equus: High beam operation

To turn on the high beam headlights, push the lever away from you. Pull it back for low beams.
The high beam indicator will light when the headlamp high beams are switched on.
To prevent the battery from being discharged, do not leave the lights on for a prolonged time while the engine is not running.
WARNING
Do not use high beam when there are other vehicles. Using high beam could obstruct the other driver's vision.

To flash the headlights, pull the lever towards you. It will return to the normal (low beam) position when released. The headlight switch does not need to be on to use this flashing feature.
