The Land Rover Range Rover side marker utilizes a 12961 bulb size for illumination purposes across various production periods. Available data covers a continuous span from 1996 through 2012.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Land Rover Range Rover uses the 12961 bulb for the front side marker across the 1996-2012 model years, with the single exception of the 1994 model year, which uses the 232 bulb instead.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The 232 is an ANSI-standard designation used in the US and Canada, referring to a festoon bulb with an SV8.5 base, rated at 12V and 3W.
The T10 wedge base of the 12961 and the SV8.5 festoon base of the 232 are physically incompatible socket types, meaning the two bulbs are not interchangeable.
The 12961 and 232 also differ in wattage, with the 12961 rated at 5W and the 232 rated at 3W, which reflects a difference in light output between the two bulb types.
For the 2006 model year Range Rover, the 12961 front side marker bulb applies specifically to vehicles from chassis number 6A000001 onward.
For the 2005 model year Range Rover, the 12961 front side marker bulb applies specifically to vehicles up to and including chassis number 5A999999.
The chassis number qualifiers on the 2005 and 2006 entries indicate a mid-cycle production change, where vehicles on either side of that boundary may have different front side marker socket configurations.
