⚠️ Fitment & Installation Note

Confirm the original bulb number, voltage, wattage, base type, pin position, contact configuration, bulb dimensions, and intended lamp function before ordering. Similar-looking bulbs may not be electrically or physically interchangeable.

Switch off the vehicle and allow the lamp assembly to cool before replacement. Avoid touching the bulb with oily or dirty hands, and inspect the socket for corrosion, heat damage, looseness, or burned contacts.

Install the bulb securely without excessive force. Test all lighting functions after installation and replace damaged sockets or wiring rather than relying on a new bulb to correct an electrical fault.
