Car Dome Interior Light Delay Switch Timer (1 to 25 Seconds, 1A, 12V Positive Switching)

In many modern cars, the interior dome light stays on for a few seconds (1-25 seconds) after the doors are closed, providing a helpful delay before turning off. This feature may not be present in older cars, so this module is designed to add it.

How It Works:

• When a door opens, the dome light will turn on immediately.
• When the door is closed, the light remains on for an adjustable delay (1-25 seconds) before turning off.

Features:

• Compatible with both LED and incandescent lights, up to a maximum load of 10A (120 watts).
• Note: For use in cars with a positive door-switching signal only.
• LED indication for operational status.
• Protected against reverse supply voltage.
• Adjustable delay time with a 100K trimmer (turn clockwise to increase time).

Specifications:

• Power Supply: 12V DC.
• Connections:
  • Red wire: Positive power input (+12V).
  • Black wire: Negative ground.
  • Yellow wire: Connect to the cut end of the wire leading to door switches.
  • White wire: Connect to the door switch terminal on the dome light.
• For added safety, the red wire can be connected through a 3-10A fuse, depending on the light wattage.

Installation Guide:

1. Locate the three connectors on the dome light:
   • One for ground.
   • One directly connected to the battery.
   • One connected to the door switches, which are wired in parallel to the positive side.
2. Cut the wire leading to the door switches.
3. Connect the yellow wire from the module to the cut end leading to the door switches.
4. Connect the black wire to negative (ground), red to positive, and white to the door switch terminal on the dome light.
5. Adjust the delay time using the trimmer as needed.

This module provides an easy way to add a delay feature to older cars, making the dome light more functional and user-friendly.
