This is the insert for the Lucas ST38 "Pork Pie Lamp" as used on the MG PA, NA, PB, NB, and numerous other British vehicles.
It provides functions for tail, brake, turn signal, and license plate lights.
There are two different configurations available:
This is the variation where no relay is required as the insert is comprised of three separate circuits plus license plate light. Since this variation is simpler to use, it requires that the brake and turn signal are less bright as each function uses less that the full complement of LEDs.
This variation requires the use of an external relay such as the Lucas DB10 to control the brake light segment. When the turn signal is activated, the brake function on that side is deactivated and used for the turn signal instead. Although the wiring in the car is more complicated, it does result in a brighter brake light as the entire number of LEDs are used for the brake and turn signal. The relay is not included and must be acquired separately.
The price is for a pair of lamp inserts sufficient for one vehicle.
This includes the insert only and does not include the housing, lens, or external relay.
