Need Help w/ Depo LED tail lights

[MytinyBoxster]

I bought a pair of Depo LED tailights. The lights have 1 bank of LEDs as brake-lights, and a second bank of LEDs for fog lights. I connected the foglight bank of LEDs to the brake light bank but the foglight bank does not light up? I did red wire to red, black wire to black. I was hoping I could have both light up as my brake lights. Can anyone advise me why they are not lighting up? What can I do?

Thanks
