The Land Rover LR2 turn signal requires a PY21W bulb size for the lighting system. Data for the specific bulb requirements covers the period from 2015 through 2015.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The PY21W is an ECE-standard single-filament amber bulb rated at 12V and 21W, fitted with a BAU15s bayonet base. Its amber glass envelope produces the required turn signal color without relying on a colored lens, which distinguishes it from clear-glass alternatives.
The 12496 is a Philips/Osram part number designating a 12V halogen bulb for specialty applications. It appears across both front inner and rear turn signal positions on the Land Rover LR2, making it the most frequently specified bulb type in these specifications overall.
The 12961 is a Philips part number for a miniature wedge-style T10 bulb with a W2.1x9.5d base, rated at 12V and 5W. Its low wattage rating places it well below the 21W output of the PY21W, reflecting its use in a lower-intensity front outer turn signal position.
The BAU15s base of the PY21W is an offset single-contact bayonet fitting. The pin offset is intentional, as it prevents the bulb from being seated in a socket designed for a symmetrical base, reducing the risk of incorrect installation.
The front outer turn signal on the LR2 uses the 12961 across the 2011-2015 model years, and also for 2008 vehicles produced up to chassis number 8H999999, indicating a mid-production specification that applied only to a defined portion of that model year's output.
The front inner turn signal position on the LR2 alternates between the PY21W and the 12496 across different model years. The two bulb types use different base designs and wattage ratings, meaning they are not interchangeable with one another.
For the 2008 Land Rover LR2, the front turn signal and front inner turn signal positions both list the PY21W, while the rear turn signal lists the 12496, indicating that a single model year could require more than one bulb type across its turn signal circuit.
The rear turn signal position on the LR2 uses the PY21W for the 2009 and 2012 model years, while surrounding years specify the 12496. Because these two bulbs have different base types, year-specific verification is necessary before replacement.
The W2.1x9.5d base of the 12961 is a wedge-type fitting, which is retained in its socket by the tension of the base contacts rather than by a bayonet lock or screw mechanism, a construction common to low-wattage miniature automotive bulbs.
No front outer turn signal entry is listed for the 2009 and 2010 model years in these specifications. Those years instead carry a Front Turn Signal entry using the PY21W, suggesting a difference in how the turn signal assembly was categorized or configured for that period.
