Extended Product Information

FAQs

Is this bulb suitable for all vehicles?

This is an H4 type bulb. Please check your vehicle's owner manual or the existing bulb to confirm if H4 is the correct fitment for your headlights.

Can I replace just one headlight bulb?

While you can replace a single bulb, it is highly recommended to replace headlight bulbs in pairs. This ensures consistent light output, color, and beam pattern between both headlights, which is important for visibility and road safety.

How long will this bulb typically last?

Osram ORIGINAL LINE bulbs are known for their long lifespan and reliability. While exact life varies based on usage and conditions, they are designed to provide superior illumination without significant dimming over time.

What does 'E marked' mean?

'E marked' indicates that the bulb complies with European standards for safety and performance, making it legal for use on roads in most countries.

Can I touch the glass part of the bulb when installing it?

No, it is crucial not to touch the glass surface of the bulb with bare fingers. Oils from your skin can cause the bulb to overheat and fail prematurely. Always use a clean cloth or gloves during installation.

What is the difference between 60W and 55W?

For an H4 twin-filament bulb, the 60W rating typically refers to the high beam power, and the 55W rating refers to the low beam power. This bulb provides a stronger light output when the high beams are activated.

Does this bulb require any special wiring or modifications?

No, the Osram 64193 is designed as a direct replacement for standard H4 bulbs and does not require any special wiring or modifications to your vehicle's electrical system.

Troubleshooting

Bulb does not light up

Ensure the bulb is correctly seated and the retaining clip is secure. Check the electrical connection to the bulb and verify the vehicle's fuse for the headlight circuit is intact. Test the bulb in another compatible vehicle if possible.

Premature bulb failure

Ensure the glass of the bulb was not touched during installation. Check for excessive vibration in the vehicle, which can shorten bulb life. Verify the vehicle's voltage supply is stable.

Dim or uneven light output

Confirm the bulb is the correct type (H4) and properly installed. Clean the headlight lens. Check and adjust the headlight aim; the bulb may need to be adjusted for proper beam cutoff.

Setup, Compatibility & Care

Compatibility:

This bulb is an H4 type with a P43t base, commonly found in many vehicles. Always confirm your vehicle's manual or existing bulb type before purchasing to ensure compatibility.

Setup (Installation):

  1. Ensure the vehicle's ignition is off and the headlight assembly is cool to the touch.
  2. Access the back of the headlight unit, typically by removing a dust cover.
  3. Disconnect the electrical connector from the old bulb.
  4. Release the retaining clip holding the bulb in place.
  5. Carefully remove the old bulb.
  6. Insert the new Osram H4 bulb, ensuring it is seated correctly in the housing.
  7. Secure the bulb with the retaining clip.
  8. Reconnect the electrical connector.

  10. Crucially, avoid touching the glass surface of the new bulb with bare fingers. Oils from your skin can create hot spots and shorten the bulb's lifespan. Use a clean cloth or gloves.

Care:

  • Regularly check headlight aim and adjust if necessary, especially after bulb replacement.
  • Keep headlight lenses clean for optimal light output.
  • Replace bulbs in pairs (both left and right) to ensure consistent light output and color.
