- Drill Pilot Holes (if necessary): If not using existing holes, mark and drill appropriate pilot holes for the mounting screws. The light features a "twist, lock & go" bezel for easy installation, which typically involves securing the base and then twisting the bezel into place.
- Wiring Connections: The light comes with 3 wires.
- Identify the positive (+), negative (-), and auxiliary (if applicable, for dual-function lights) wires.
- Connect the positive wire to a 12V power source.
- Connect the negative wire to a suitable ground point on the vehicle chassis.
- Secure all connections using wire crimps, solder, and insulate with electrical tape or heat shrink tubing to prevent short circuits and ensure a waterproof seal.

Operating Instructions
The GG Grand General 75849 LED light operates as a standard 12V lighting unit. Once properly wired and installed, its operation is controlled by the vehicle's electrical system, typically through a switch or integrated lighting circuit.
- Activation: The light will illuminate when power is supplied to its positive wire and the negative wire is grounded. This is usually controlled by the vehicle's existing lighting switch (e.g., marker lights, turn signals, or auxiliary light switch).
- Power Requirements: Ensure the power source is a stable 12V DC supply.
Maintenance
Minimal maintenance is required for the GG Grand General LED light due to its durable and waterproof design.
- Cleaning: Periodically clean the lens and bezel with a soft cloth and mild soap and water to remove dirt and debris. Avoid abrasive cleaners that could scratch the surface.
- Inspection: Regularly inspect the wiring connections for any signs of corrosion, fraying, or loose connections. Ensure the light remains securely mounted.
- LED Longevity: LEDs have a long lifespan and typically do not require replacement under normal operating conditions.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not illuminate. | No power supply; faulty wiring connection; blown fuse; incorrect grounding. | Check 12V power source with a multimeter. Verify all wire connections are secure and properly insulated. Inspect vehicle's fuse box for blown fuses. Ensure the ground connection is clean and solid. |
| Light flickers or is dim. | Loose connection; insufficient voltage; corroded wiring. | Tighten all connections. Check voltage at the light's input. Clean any corroded terminals or replace damaged wiring. |
