4. Installation Guide
The Morimoto XB LED Foglights are designed for a straightforward plug-and-play installation. The process may vary slightly depending on your vehicle's make and model. For specific vehicle disassembly instructions, consult your vehicle's service manual or an online resource.
4.1. Pre-Installation Steps
- Gather Tools: You will typically need basic hand tools such as screwdrivers, wrenches, and possibly trim removal tools.
- Disconnect Battery: For safety, disconnect the negative terminal of your vehicle's battery.
- Access Fog Light Area: Depending on your vehicle, this may involve removing fender liners, bumper covers, or accessing from underneath the vehicle.
4.2. Step-by-Step Installation
- Remove Existing Fog Lights: Carefully unclip or unscrew the factory fog lights from their mounting points. Disconnect the electrical connector from the back of the factory fog light. For some vehicles like the F-150, butter knives (taped to prevent scratching) can be used to unlock tabs and 'pop' them out from the front after removing the adjusting screw and spring.
- Connect New Fog Lights: Take one Morimoto XB LED Foglight assembly. Connect the provided pigtail to the fog light. Then, connect the pigtail to your vehicle's factory fog light harness. Ensure the connection is secure. Note that these lights are continuity sensitive; ensure correct positive and negative wiring. For some Ford F-150 models, with the wire lock on top, the positive wire is on the left for both driver and passenger sides. Confirm polarity before fully seating wires into the plug, as removal can be difficult.
- Secure New Fog Lights: Mount the Morimoto XB LED Foglight assembly into the factory fog light opening. Ensure all mounting points align and the light is securely fastened.
- Repeat for Other Side: Perform steps 1-3 for the other fog light.
- Adjust Aim: The aim of the fog lights can be adjusted just like stock units using the integrated adjustment mechanism. It is recommended to adjust the aim on a level surface, ensuring the beam pattern is low and wide, not pointing upwards.
- Reconnect Battery: Once both fog lights are installed and secured, reconnect the negative terminal of your vehicle's battery.
- Test Functionality: Turn on your vehicle's fog lights to ensure they are functioning correctly.

5. Operating Instructions
The Morimoto XB LED Foglights operate in conjunction with your vehicle's existing fog light switch. Once installed, they will function identically to your factory fog lights.
- Activation: Turn on your vehicle's fog lights using the dedicated switch or control on your dashboard or steering column.
- Beam Pattern: These fog lights produce a super wide and low beam pattern, designed to illuminate the road directly in front of and to the sides of your vehicle, especially useful in conditions with reduced visibility such as fog, rain, or snow. They are not intended to be driving lights that project far down the road.
- Deactivation: Turn off your vehicle's fog lights using the same switch or control.
6. Maintenance
The Morimoto XB LED Foglights are designed for durability and require minimal maintenance.
- Cleaning: Clean the polycarbonate lens periodically with a soft cloth and mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the lens.
- Inspection: Periodically inspect the fog lights for any signs of damage, loose connections, or debris accumulation. Ensure the housing remains free of dirt and mud to allow for proper heat dissipation.
- No User-Serviceable Parts: The internal LED components are not user-serviceable. Do not attempt to open the sealed housing.
7. Troubleshooting
If you encounter issues with your Morimoto XB LED Foglights, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fog lights do not turn on. | Loose or incorrect electrical connection. Blown fuse in vehicle's fog light circuit. | Check all electrical connections, ensuring they are secure and correctly polarized. Refer to Section 4.2. Inspect and replace the vehicle's fog light fuse if necessary. |
| One fog light is not working. | Faulty connection to that specific light. Damaged light assembly. | Verify the connection to the non-functioning light. Ensure proper polarity. If connections are good, contact Morimoto support for warranty assistance. |
| Light output is dim or flickering. | Insufficient power supply. Loose connection. | Ensure the vehicle's electrical system is functioning correctly. Check all connections for tightness. |
| Condensation inside the lens. | Extreme temperature changes or high humidity. Compromised seal (unlikely due to IP67 rating). | Minor condensation may dissipate with normal operation. If persistent or excessive, contact support. |
If you are unable to resolve an issue using the troubleshooting steps above, please contact Morimoto customer support for further assistance.
