what are the specs for the taillight park /brake bulb in the LR3 V8 HSE? The two filament type?

Answer 1

That would be a B1157.
The center of the major filament is 19.10mm above zero, on the primary axis.
· In addition to an offset in the primary axis, the source’s filament has another offset(s). With the primary axis set to +Z and the secondary axis set to +Y, the major filament’s true center point is at (1.25, 0.00, 19.10) in (X, Y, Z).
· This bulb has an output of 402 Lumens (major filament) and 38 Lumens (minor filament), while running at 12.8V/2.10A and 14.0V/0.59A, respectively.

Answer 2

Do you mean number of lumens, amp draw, outside diameter, or what?
