The brake lights on the sides do not work, however the led strip does. This mean that the pedal switch is good. Also, from what I've read the 3 lights are on the same fuse, so it can't be the fuse.

Is there a separate fuse for the 3rd led?

It's unlikely that the bulbs both burnt out together. What are your thoughts?

 

I'd swap the bulbs first and or check for voltage
