Purpose of Small Rear Lights ?
 

There are 4 x small circular rear lights on this model. 2 x lights on each side that are closest to the trunk/boot. I know that the bottom left light is for reverse. But, what is the purpose of the other 3 x small rear lights?

The reverse light is on when in reverse. But, the other 3 x lights never turn on. I have tested for all scenarios (lights on, brake lights, reverse, indicators), with no luck.

What is the purpose of these 3 x small rear lights and when should they appear on?

How do i test the functionality of these lights?
