Anyone know if the 2010-2013 gauge cluster is compatible with the 2006-2009 IS? I read somewhere here that the the 2010-2013 cluster has a different needle lighting method for the tachometer and speedometer because the leds are no longer on the needle itself, but on the cluster. This makes all needles have the same color, whereas the 2006-2009 one has different shades of the same color because of the way the needles are lit up.
