MPH light on speedometer dims ???
The MPH light on my speedometer dims and then brightens again.
The other lights do not do this. Just the MPH light.
Anyone else have this happen?

The apparent change in speedometer brightness is corelated to the speed at which you are driving.There is a receptor in the brain that releases seratonin as the pulse, respiration and blood pressure increase. The release of seratonin causes the pupils to dilate and let in more light.
When you drive slowly you get bored,your pupils constrict and let in less light.

It is light sensitive. If you watch it long enough you'll notice that it brightens and dims in connection with the HUD. Of course if you watch it that long you'll probably hit something.
