5. Operating Instructions
5.1 Turning On/Off
The Morimoto XB LED Fog Lights operate in conjunction with your vehicle's factory fog light switch. Refer to your Subaru Legacy owner's manual for specific instructions on how to activate and deactivate the fog lights.
5.2 Aiming the Fog Lights
Proper aiming of fog lights is crucial for optimal performance and to avoid blinding oncoming traffic. The Morimoto XB LED Fog Lights feature integrated height adjusters for precise aiming.
- Preparation: Park your vehicle on a level surface approximately 25 feet (7.6 meters) from a wall or garage door. Ensure tire pressure is correct and the vehicle is unloaded.
- Identify Adjustment Screw: Locate the aiming adjustment screw on the back of each fog light assembly (refer to Image 4.1).
- Adjust Aim: Turn on your vehicle's fog lights. Use a Phillips head screwdriver to turn the adjustment screw. Turning clockwise will typically raise the beam, and counter-clockwise will lower it.
- Target Aim: The top edge of the fog light beam should typically be aimed at or slightly below the center of the fog light housing itself when projected onto the wall. The beam should spread wide and low. Consult local regulations or a professional for precise aiming standards in your region.
- Final Check: After adjustment, take the vehicle for a short drive to confirm proper aiming and ensure visibility is improved without causing glare to other drivers.
6. Maintenance
The Morimoto XB LED Fog Lights are designed for minimal maintenance due to their durable construction and LED technology.
- Cleaning: Periodically clean the polycarbonate lenses with a soft cloth and mild soap and water. Avoid abrasive cleaners or harsh chemicals, as these can damage the lens surface.
- Inspection: Regularly inspect the fog lights for any signs of damage, loose connections, or debris accumulation. Ensure the mounting hardware remains secure.
- No User-Serviceable Parts: The LED components are integrated and not designed for user replacement. Do not attempt to disassemble the fog light housing.
