Housing and lens are NOT included. The kit only includes the LED light boards.
This is the insert for the Lucas ST38 "Pork Pie Lamp" as used for a backup lamp or 3rd brake light.
NOW AVAILABLE FOR EITHER 6 OR 12 VOLT VEHICLES
It provides functions for tail, brake, turn signal, and license plate lights.
There are two different configurations available:

2 SEGMENT
This is the variation where no relay is required as the insert is comprised of two separate circuits ( a -  tail/brake and b - turn signal) 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 than the full complement of LEDs. This is the ONLY configuration where the turn signal can be AMBER.

1 SEGMENT
This variation is intended for use as a 3rd brake light. 

The price is for a single lamp insert.
This includes the insert only and does not include the housing, lens, or external relay.
