FAQs
Are these bulbs legal for road use?
Yes, as OEM replacement parts, they meet standard automotive safety requirements.
Can I touch the glass with my bare hands?
It is recommended to use gloves or a clean cloth to avoid getting oils on the glass, which can reduce the bulb's lifespan.
How many bulbs are included in a pack?
Each pack contains 10 individual bulbs.
Is this a dual-filament bulb?
Yes, the P27/7W specification indicates it supports two brightness levels, typically used for combined tail/brake or parking/turn functions.
What does W2.5x16q refer to?
This refers to the specific wedge-style base size and configuration that allows it to lock into the vehicle's light socket.
Troubleshooting
Bulb does not illuminate
Check that the bulb is fully seated in the socket and verify that the vehicle fuse for that light circuit is not blown.
Rapid flashing (hyper-flashing)
Ensure the correct wattage bulb is installed; if using as a turn signal, a load resistor may be needed if switching from a different bulb type.
Bulb flickers
Clean the metal contacts in the socket with an electrical contact cleaner to remove any oxidation.

Setup, Compatibility & Care
Before installation, ensure your vehicle is completely powered off to prevent electrical shorts. Use a clean cloth or gloves to handle the bulb, as oils from your skin can create hot spots on the glass surface and lead to premature failure. To install, remove the old bulb by pulling it straight out of the socket and gently press the new bulb into place until it clicks. Always check the manual for your specific vehicle make (VW, Opel, Kia, Jeep, or Chrysler) to confirm that the W2.5x16q socket is the correct match for your light housing.
