Give your cluster a little whack with your palm, it looks like one of the bulbs isn't lighting up.
Mine did this initially until I adjusted them in the sockets.
Edit: From the page-
Notice:All LED bulbs have to be plugged in a certain way,it has Positive and negative, so if they don't work at first, quickly take them out, turn them around 180 degree, and put them back in again.
They are bigger than the stock ones but they fit.
