Headlight: mainly installed in the front of agricultural machinery, used to illuminate the working road or working area in front. Headlights usually have high brightness, which can provide a clear field of vision at night or in low light conditions, and help drivers operate agricultural machinery accurately.

When the agricultural machinery truck needs to turn (such as turning in the field or changing lanes on rural roads), turning on the turn signal can remind the rear vehicles, pedestrians and surrounding workers to avoid, thus reducing the collision risk at intersections or bends. Example: When a tractor pulls a farm tool to turn left in a narrow road, the left turn signal flashes to remind the opposite vehicle to stop and wait in advance.

Lane change warning function If it is necessary to change lanes (such as overtaking other agricultural machinery or vehicles) when driving on roads or main roads in the field, the turn signal can clearly inform other traffic participants of the driving intention of agricultural machinery, so as to reduce the collision or rear-end collision accidents caused by "sudden lane change".
