OXILAM M5S H7 LED Bulb Instruction Manual

1. Product Overview

The OXILAM M5S H7 LED bulbs are designed as a direct replacement for standard H7 halogen bulbs in automotive applications. They feature high brightness, a focused beam pattern, and an efficient cooling system for extended lifespan. These bulbs provide a 6500K cool white light, enhancing visibility during night driving.

2. Safety Information

• Ensure the vehicle's ignition is off and the battery is disconnected before installation to prevent electrical shock.
• Allow existing halogen bulbs to cool down completely before handling, as they can be very hot.
• Avoid touching the glass part of the LED bulb directly with bare hands. Use gloves or a clean cloth to prevent oil residue from affecting performance or lifespan.
• Always wear appropriate safety eyewear during installation.
• Verify that the bulb type (H7) is compatible with your vehicle's headlight assembly before attempting installation.
• Do not modify the bulbs or vehicle wiring unless explicitly instructed by a qualified professional.

3. Installation Guide

The OXILAM M5S H7 LED bulbs are designed for a quick and straightforward installation, typically taking about 5 minutes per bulb. No additional adapters are required for most vehicles due to their 1:1 size ratio with original halogen bulbs.

1. Preparation: Park your vehicle on a level surface, turn off the engine, and engage the parking brake. Open the hood.
2. Locate the Headlight Assembly: Identify the back of the headlight assembly where the H7 bulb is housed.
3. Remove Old Halogen Bulb: Disconnect the electrical connector from the back of the halogen bulb. Depending on your vehicle model, you may need to twist or unclip a retaining spring to release the bulb. Carefully pull out the old halogen bulb.
4. Insert New LED Bulb: Insert the OXILAM H7 LED bulb into the headlight housing. Ensure the LED chips are oriented correctly (typically at 3 and 9 o'clock positions for optimal beam pattern). Twist or secure the retaining clip to lock the LED bulb in place.
5. Connect Electrical Connector: Connect the vehicle's original electrical connector to the new LED bulb. The bulbs are non-polarity sensitive, simplifying this step.
6. Test Functionality: Turn on your vehicle's headlights to ensure both LED bulbs are functioning correctly. Check for proper beam pattern and brightness.

4. Operating Instructions

The OXILAM M5S H7 LED bulbs are designed to provide superior illumination for enhanced driving safety. Once installed, operate them as you would your standard vehicle headlights.

• Enhanced Night Vision: These bulbs deliver 40,000 lumens and 100 watts per pair, offering significantly brighter light (up to 900% brighter than stock halogen bulbs). This improves visibility of road signs and obstacles.
• Cool White Light: The 6500K cool white light provides a clear and modern illumination, reducing eye strain during extended night driving.
• Focused Beam Pattern: The 1:1 filament design and 0.039-inch ultra-thin chip spacing ensure a 360° light illumination with a wide and penetrating cut-off line, preventing glare for oncoming drivers.

5. Maintenance

The OXILAM M5S H7 LED bulbs are designed for long-term, maintenance-free operation. Their robust construction and advanced cooling system contribute to an extended lifespan.

• Efficient Cooling System: The bulbs feature a full aviation aluminum body, copper baseboard, and a built-in 12,000 RPM silent cooling fan. This system provides fast and stable heat dissipation, maximizing the lifespan and brightness of the LED bulbs to over 10 years, even with daily use.
• Cleaning: Periodically clean the exterior of your vehicle's headlight lenses to ensure maximum light output. Use a soft cloth and appropriate automotive cleaning solutions.
• Inspection: Regularly inspect the bulbs for any physical damage or loose connections.

6. Troubleshooting

If you encounter any issues with your OXILAM M5S H7 LED bulbs, refer to the following common troubleshooting steps:

• Flickering or Dash Errors: These bulbs are equipped with a 2025 latest linear intelligent IC driver, offering 99%+ vehicle compatibility to prevent flickering, radio interference, and dash errors. However, for some highly sensitive vehicle models, an additional CANbus decoder may be required to resolve these issues. Contact OXILAM support if this occurs.
• Bulb Not Lighting Up:
  • Check the electrical connection to ensure it is secure.
  • Verify that the vehicle's fuse for the headlights is intact.
  • Ensure the bulb is correctly seated and locked into the headlight housing.
• Uneven Light Output:
  • Confirm that the LED chips are oriented correctly (3 and 9 o'clock positions) within the headlight assembly.
  • Inspect the headlight housing and lens for any obstructions or damage.
