Why are the bulb sockets on the back of the Tach/speedo cluster blue and gray? Does it make a difference where they are used? The gray seem to be in the center of the cluster for Left and right directional and two sockets below that.. Does it make a difference.

Never really paid any attention to them, but it's possible the color difference has to do with some sockets being used for cluster illumination, and others for indicators lamps. Question

Just a guess into another possibility...they could be from different vendors.  The color could be a quick way to determine one vendor from another and they're simply dumped into the same parts bin at the assembly plant.
