Hyundai Santa Cruz Side Marker Bulb Size

Additional Notes

• The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which uses a W2.1x9.5d base. This base type features a wedge-style connection with no separate metal contacts, relying instead on the glass envelope itself to make electrical contact within the socket.
• The 12961 operates at 12 volts and draws 5 watts, placing it in the low-wattage range typical of parking and marker lighting applications where heat output and power consumption are kept minimal.
• The T10 designation refers to the bulb's tubular form factor, with the number indicating a width of 10 units in the relevant measurement convention. This form factor is widely used across the automotive industry for side marker, parking, and interior lighting positions.
• The Hyundai Santa Cruz uses the 12961 bulb for its side marker position across the 2023-2024 model years, indicating a consistent socket specification across both years.
• The W2.1x9.5d base is a standardized wedge base defined by international automotive bulb standards, meaning cross-referenced equivalents from other manufacturers sharing this base type and the same 12V/5W rating are generally interchangeable with the 12961 in this application.
