Extended Product Information

FAQs

Are these bulbs road legal?

Yes, these bulbs are E marked, which means they comply with European safety and performance standards for road use.

Can I use these for both high and low beam?

Yes, these bulbs are suitable for both dipped (low) and main (high) beam applications, provided your vehicle uses an H7 bulb for those functions.

What happens if I touch the glass?

If you touch the glass, clean it thoroughly with rubbing alcohol and a lint-free cloth before installing to remove oils that can damage the bulb.

How long is the warranty?

This product is covered by a 3-month manufacturer guarantee.

Does this pack include 10 individual bulbs?

Yes, the pack contains 10 separate H7 12V 55W bulbs.

Troubleshooting

Bulb fails to illuminate after installation

Check that the electrical connector is pushed fully into the base and verify that the retaining clip is properly seated.

Light appears dim or flickers

Inspect the wiring harness for corrosion or loose connections, as a poor electrical contact is a common cause of flickering.

Bulb failed shortly after installation

Ensure the glass was not touched with bare fingers, as oil residue causes heat spots that can shatter the bulb.

Pros and Cons

Pros

  • High value 10-pack provides a cost-effective solution for frequent replacements
  • Meets industry-standard specifications for 12V 55W H7 bulbs
  • E marked for full legal road use
  • Standard design ensures easy installation without adapters or modifications

Cons

  • Not an upgrade for users seeking increased brightness or cooler color temperatures
  • Requires careful handling to avoid skin oils touching the glass
  • Includes a relatively short 3-month manufacturer guarantee
  • Standard halogen lifespan compared to LED or Xenon alternatives

Setup, Compatibility & Care

Before installation, always consult your vehicle owner's manual to verify that your headlight system specifically requires an H7 bulb.

Installation Tips:

  1. Ensure the headlight switch is in the 'off' position and the engine is cool to prevent burns.
  2. Access the headlight housing from behind the engine bay; you may need to remove a dust cover.
  3. Disconnect the electrical connector and unclip the retaining wire holding the bulb in place.
  4. Important: When handling the new bulb, hold it by the plastic base only. Touching the glass with bare fingers can deposit oils that lead to premature bulb failure or overheating.
  5. Align the two pins of the PX26D base with the socket, insert, and secure the retaining wire.
  6. Reconnect the wiring and test the light before replacing any covers.
