Installation Guide
The Marsauto M1S LED bulbs feature a 1:1 design for easy, plug-and-play installation, typically completed within 3 minutes per bulb. No external drivers or complex wiring are required.
1. Compatibility Check
Before installation, confirm that these H11/H8/H9 bulbs are compatible with your vehicle's fog light sockets. These bulbs are designed as a direct replacement for halogen bulbs. Do not attempt to replace HID or LED factory bulbs with this product.

2. Installation Steps
- Safety First: Ensure your vehicle's engine is off and the lights are cool before beginning. Wear the provided gloves to avoid touching the bulb surface.
- Locate Bulb: Identify the fog light housing on your vehicle. Access may vary by vehicle model (e.g., from under the hood or wheel well).
- Remove Old Bulb: Disconnect the electrical connector from the existing halogen bulb. Then, carefully twist or unclip the old bulb to remove it from the housing.
- Insert New LED Bulb: Insert the Marsauto M1S LED bulb into the fog light housing. Ensure it is seated correctly and securely. The 1:1 design minimizes fitment issues.
- Secure and Connect: Twist or clip the LED bulb into place to secure it. Reconnect the electrical connector to the new LED bulb.
- Test: Turn on your vehicle's fog lights to confirm proper operation.

3. Adjusting the Beam Angle (if necessary)
The Marsauto M1S bulbs feature a 360° adjustable lock ring, allowing you to fine-tune the beam pattern for optimal light output and to avoid blinding oncoming traffic. If the beam pattern appears incorrect after installation, you can adjust the bulb's orientation:
- Loosen the small screws on the adjustable ring (a small Phillips screwdriver may be required).
- Rotate the bulb body within the lock ring until the LED chips are positioned vertically (flat sides at 9 and 3 o'clock) for the best beam pattern.
- Tighten the screws to secure the adjusted position.

Operation
Once installed, the Marsauto M1S LED fog light bulbs operate like your vehicle's original bulbs. Simply activate your vehicle's fog light switch to turn them on. These bulbs provide a significantly brighter, 6000K cool white light, enhancing visibility in adverse weather conditions such as fog, rain, or snow.

Maintenance
Marsauto M1S LED bulbs are designed for minimal maintenance due to their durable construction and efficient design. They feature a fanless design, eliminating moving parts that can wear out, and an IP68 waterproof rating for protection against environmental elements.
- Cleaning: If necessary, gently wipe the bulb's lens with a soft, dry cloth. Avoid abrasive cleaners or materials.
- Inspection: Periodically check the bulbs for any signs of damage or loose connections.
- Lifespan: With an estimated lifespan of up to 60,000 hours, these bulbs are built to last, significantly reducing the need for frequent replacements.
