Mitsubishi Eclipse Cross License Plate Bulb Size

Additional Notes

• The H11 halogen bulb is a single-filament wedge-base type rated at 55 watts and commonly used in low-beam headlight applications, though its presence here in a license plate position reflects a less typical fitment choice for that location.
• The 12961 is a T5 wedge-base bulb operating at 12 volts and 5 watts, a form factor widely associated with license plate and interior lighting duties across many vehicle lines.
• The Mitsubishi Eclipse Cross uses the 12961 bulb for its license plate position across the 2018-2020 model years.
• The 2023-2024 Eclipse Cross uses the H11 bulb for the license plate position, representing a different bulb type from the one used in earlier model years.
• The H11 and 12961 are not interchangeable. They differ in base type, wattage, physical size, and connector design, meaning a bulb from one fitment group cannot be substituted into a vehicle requiring the other.
• The T5 wedge base of the 12961 allows direct plug-in installation without a locking connector, while the H11 uses a twist-lock bayonet-style housing, making the two mechanically incompatible at the socket level.
• At 55 watts, the H11 draws considerably more power than the 5-watt 12961, a factor relevant when considering LED retrofit compatibility and circuit load tolerances for each respective model year group.
