Product Overview

The Philips Ultinon Access LED headlight bulbs are designed to provide a superior beam performance compared to traditional halogen bulbs. They offer a plug-and-play installation, are energy-efficient, and provide a bright, 6000K white light for enhanced visibility and safety.

Installation Instructions

  1. Ensure the vehicle's engine is turned off, and the headlights are cool to the touch before starting the installation.
  2. Open the hood and locate the back of the headlight assembly where the current H4 bulb is situated.
  3. Disconnect the power connector from the back of the bulb.
  4. Remove the existing H4 bulb by turning it counterclockwise and gently pulling it out of the headlight housing.
  5. Take the new Philips Ultinon Access LED bulb and insert it into the headlight housing. Align the tabs correctly and turn the bulb clockwise to secure it.

Troubleshooting Tips

  • Flickering or Unstable Light: If the LED bulbs flicker or are unstable, disable the "cold check" feature using a compatible vehicle scanner tool. For certain vehicles, a CANbus adapter may be necessary to prevent errors.
  • Error Messages: After installation, if your vehicle's dashboard indicates an error message, you may need to code the vehicle to recognize the LED retrofit. Tools like Bimmercode can be used for BMW vehicles.
  • Improper Beam Pattern: Ensure that the LED bulb is properly seated and aligned within the headlight assembly. Misalignment can cause an incorrect beam pattern.
  • Non-functioning Bulb: If the bulb does not turn on, check the power connector for a secure connection and ensure that there is no damage to the bulb itself.
