Illuminated Door Sills not working

I have a Blizzard Pearl 2012 Toyota Prius PPP ediition, I have owned it since August of 2013 and absolutely love it, the upgraded stiffer suspension is awesome.
I can make 60 mph turns on freeway ramps with little to no body roll, it an insane feeling.

Now to my problem, can any of the other PPP owners tell me if all 4 door sills light up, only the passenger side door sill has ever lit up since I bought it, I thought that was the way it was meant to be but after reading on this forum it appears they all light up or at the very least both front doors light up.

I looked closely at the back door sills and they do not to be the same as the front ones as though they might not light up, guess I will have to remove them to check if they have power runnig to them

Do each of them have fuses? can you guys tell me where to look .
