Each individual vehicle is necessarily equipped with various cornering light devices, which, in turn, operate in an intermittent mode. It should be noted that the main current relay is responsible for the well-coordinated operation of these devices.

These devices mean electronic or electrical devices, through which circuits are closed and opened to form intermittent signals, which in turn will warn other road users about performing a certain maneuver.

The functions of the main current relay

When turned on, the main current relays flash, that is, they light up and go out at regular intervals, so they attract the attention of other road users, and it is quite difficult not to notice the turned on “turn signal”. The flashing of the main current relays also plays another role - it does not allow drivers to confuse their inclusion with the operation of brake lights or the inclusion of parking lights.
