Installation Guidelines

1. Safety First: Disconnect the vehicle’s battery before working on lighting circuits to prevent electrical shock or accidental activation.
2. Remove Old Bulb: Gently twist and pull out the existing bulb from its socket. Avoid touching the glass with bare hands; use a clean cloth or gloves to prevent oil residue.
3. Insert New Bulb: Align the W3x16Q base with the socket, ensuring a snug fit. Twist until secure but avoid over‑tightening which could damage the filament.
4. Check Alignment: Verify that the bulb is correctly positioned within the housing to prevent light leakage or misdirected illumination.
5. Reconnect Battery: Reattach the battery terminals and test the lighting system. Observe for proper brightness and functionality of all associated lights.

Maintenance & Troubleshooting

• Regular Inspection: Periodically check bulbs for signs of discoloration, cracks, or filament breakage. Replace immediately if any defects are observed.
• Cleaning: Use a soft, lint‑free cloth to wipe the bulb’s glass surface. Avoid abrasive cleaners that could damage the envelope.
• Electrical Checks: If a bulb fails prematurely, inspect the wiring harness and socket for corrosion or loose connections.
• Compatibility Confirmation: Ensure the vehicle’s electrical system matches the 12 V requirement; high‑voltage systems may require different bulb specifications.
