I've been looking at these lights myself, and I'm wondering about the middle/ centre section of the red part of the lense. It looks like there are no LEDS there, but in the pictures online, there is an opening there in the back.
The centre section is your tail light - for a normal bulb. The inner LED section is the brake light, the outer LED is a fog light (for here in the UK anyway)
