The Jaguar XKE front and rear turn signal bulbs utilize a 1156 size across both positions. The replacement chart covers 1969 to 1974 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jaguar XKE uses the 1156 bulb for both its front and rear turn signals across the 1969-1974 model years.
The 1156 is a single-filament bulb, meaning it is dedicated to one lighting function rather than serving dual purposes such as combined stop and turn signal operation.
The 1156 operates at 12 volts and 21 watts, which places it within the standard range for automotive turn signal applications of that era.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin, as opposed to the dual-pin BA15d base found on some other automotive bulbs.
The 1156 conforms to ANSI standards and is specified for use in the United States and Canada, indicating it meets the regulatory and dimensional requirements of those markets.
Because the same bulb type is specified for both the front and rear turn signal positions on the Jaguar XKE, the 1156 serves as a uniform fitment across all four turn signal housings on the vehicle.
The BA15s base of the 1156 is not interchangeable with the BA15d base used on double-contact bulbs such as the 1157, despite the two types sharing a similar physical profile, as the pin configurations differ.
