Extended Product Information

FAQs

Is the Philips Vision 12496NAB2 an LED bulb?

No, this is a conventional halogen-based signaling bulb.

What does the BAU15s base mean?

BAU15s indicates that the bulb has offset pins, which prevents it from being inserted into standard BA15s (straight pin) sockets.

Can I use this bulb for brake lights?

No, this bulb is designed specifically for indicator (turn signal) applications where a yellow light is required.

How many bulbs are in a pack?

This product comes in a blister pack containing 2 bulbs.

Does this bulb comply with road regulations?

Yes, this product meets ECE homologation standards for legal road use.

What is the expected lifetime of this bulb?

The rated bulb lifetime is approximately 500 hours of operation.

Troubleshooting

Bulb does not illuminate after installation

Check that the bulb is fully seated and locked in the socket, and inspect the vehicle's fuse box for a blown indicator fuse.

Rapid flashing (hyper-flashing) of the indicator

Ensure you have installed a bulb with the correct wattage (21W); incorrect wattage can cause the vehicle's flasher relay to pulse faster.

Bulb keeps burning out frequently

Check the vehicle's electrical system for voltage spikes or loose wiring connections at the bulb socket.

Pros and Cons

Pros

  • Meets rigorous original equipment quality standards
  • Easy to install as a direct replacement
  • Reliable light output for safety
  • ECE compliant for road legality
  • Widely compatible with various vehicle makes and models

Cons

  • Conventional halogen technology has a limited lifespan compared to LED

Setup, Compatibility & Care

Installation of the 12496NAB2 is straightforward, though it is essential to ensure the vehicle is off and the lights are cooled before beginning. To replace the bulb: locate the indicator access panel, remove the old bulb by pressing and turning counter-clockwise, and insert the new bulb by aligning the pins and turning clockwise until it locks.

Compatibility Note: This bulb features a BAU15s base (offset pins). Verify your vehicle manual or the existing bulb markings to ensure this matches your current socket, as it is not interchangeable with standard BA15s (straight pin) bulbs. To prolong the life of your bulbs, avoid touching the glass with bare fingers, as oils from the skin can cause localized heating and premature failure.
