FAQs

Can these bulbs be used as a replacement for LED lights?

No, these are incandescent bulbs and should only be used in vehicles designed for traditional filament-based lighting systems.

How many bulbs are in the pack?

This workshop pack contains 10 individual 7515 bulbs.

What does the 21/5W rating mean?

It indicates a dual-filament bulb where one filament draws 21 watts (for brake or turn signals) and the other draws 5 watts (for running or position lights).

Are these bulbs street legal?

Yes, they are engineered to meet automotive manufacturing standards for use in public road vehicles.

Should I replace both bulbs at the same time?

It is highly recommended to replace bulbs in pairs to ensure balanced brightness and to avoid having the second bulb fail shortly after the first.

Troubleshooting

Bulb flickers after installation

Check the socket for signs of corrosion or loose wiring and ensure the bulb is fully seated.

Bulb does not illuminate

Verify the vehicle fuse for the specific light circuit has not blown and ensure the filament is not damaged.

Pros and Cons

Pros

  • High manufacturing standards for reliable performance
  • Convenient 10-pack is cost-effective for repairs
  • Excellent brightness and output consistency
  • Easy to install with standard W3x16q base

Cons

  • Specific to W3x16q socket vehicles
  • Requires careful handling to avoid skin oil contamination
  • Not compatible with LED-only lighting systems

Setup, Compatibility & Care

Before installation, always verify that your vehicle manual specifies a W3x16q base bulb. To install, ensure the vehicle ignition is turned off. Access the light housing assembly, remove the faulty bulb by gently twisting or pulling it from the socket, and insert the new bulb until it clicks into place. Avoid touching the glass portion of the bulb with bare hands, as skin oils can create hotspots that reduce bulb lifespan; use a clean, dry cloth or gloves when handling. Always replace automotive bulbs in pairs to ensure even brightness and wear.
