Land Rover Freelander front and rear turn signal bulbs utilize 12496 and 1157NA sizes for front applications, with 12496 and PY21W sizes specified for rear positions. The replacement chart covers 2002 through 2005 model years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Land Rover Freelander front turn signal uses the 12496 bulb for the 2002, 2003, and 2005 model years, while the 2004 model year uses the 1157NA bulb instead.
The rear turn signal on the Land Rover Freelander follows a split pattern: the 2002 and 2004 model years use the PY21W bulb, while the 2003 and 2005 model years use the 12496 bulb.
The 12496 is a Philips/Osram part number designation for a 12V halogen bulb intended for specialty applications, rather than a universal ANSI or ECE standard reference.
The 1157NA is an ANSI-standard dual-filament bulb rated at 12V with a 21W/5W output, fitted with a BAY15d bayonet base and natural amber glass, used in North American markets.
The PY21W is an ECE-standard single-filament amber bulb rated at 12V and 21W, fitted with a BAU15s bayonet base, which is the European and international market equivalent for turn signal applications.
The BAY15d base of the 1157NA and the BAU15s base of the PY21W are not interchangeable. The BAU15s base has offset pins at 7.5 degrees, while the BAY15d base has straight parallel pins, making physical substitution between the two impossible without modification.
The 1157NA is a dual-filament bulb, meaning it carries two separate circuits within one housing, whereas the PY21W is a single-filament bulb serving only one circuit. This functional difference further distinguishes the two bulb types used across the Freelander's model years.
The natural amber glass of the 1157NA produces the amber turn signal color directly from the bulb itself, rather than relying on a colored lens to filter a clear light source.
The 2004 model year is the only year in the specifications where the front and rear turn signals use different bulb types from each other, with the 1157NA at the front and the PY21W at the rear.
For the 2002-2003 and 2005 model years, the front and rear turn signal positions share the same bulb type within each respective year, both using the 12496, except for the 2002 rear position which uses the PY21W.
