Wiring Instructions:
- The two white wires must be connected to the car’s front light switch in parallel.
- Power Input:
- Red wire (+12V)
- Black wire (Ground -12V)
- Includes protection against reverse voltage.
- Must be connected through a permanent 1A fuse.

Power Supply: 12V DC
Adjustment: Two independent trimmers are used to set delay on and delay off times.
Principle of Operation:
Engine On:
When the contact switch is turned on, the timer receives a 12V+ signal, and the delay-on time starts (indicated by a red LED). Once the delay time ends, the relay activates, closing the "NO" contact and turning on the front lights. This function prevents unnecessary battery drain.
Engine Off:
When the contact switch is turned off, the 12V+ signal stops, and the delay-off time begins. After the set time expires, the front lights automatically turn off, allowing you to leave your vehicle safely in the dark.
Cycle Repeats:
If the contact switch is turned on again, the cycle restarts.
