  • Adjustable Timing Functions

    Delay ON: adjustable from 1 to 50 seconds
    Delay OFF: adjustable from 1 to 90 seconds

    Both times are adjusted independently using separate trimmers.
    Rotate clockwise to decrease the delay time.

    The module is factory-set to minimum timing values.

    Relay Output

    COM Contact: white wire
    NO Contact: 20A / 12V DC – white wire
    NC Contact: 10A / 12V DC – not wired

    The two white wires must be connected in parallel to the vehicle front light switch circuit.

    Power Supply

    Supply Voltage: 12V DC

    Red wire: +12V
    Black wire: Ground / Negative
    Orange wire: Activation input 12V+ from ignition/contact switch

    The module includes reverse polarity protection.
    It must be connected permanently through a 1A fuse.

    Operating Principle

    When the ignition/contact switch is turned ON, the timer receives a 12V signal and the Delay ON sequence starts. During this period, the red LED indicator lights up.

    After the preset Delay ON time expires, the relay activates, the NO contact closes, and the front lights turn ON automatically. This helps reduce battery load during engine startup.

    When the ignition/contact switch is turned OFF, the 12V activation signal disappears and the Delay OFF sequence starts.

    After the preset Delay OFF time expires, the relay switches OFF and the front lights turn OFF automatically. This function provides temporary illumination after leaving the vehicle in dark environments.

    Turning the ignition ON again restarts the cycle.
