Abstract
The present invention relates to a meter suitable for use in vehicles. The meter has a polarizing window which allows light having a vertical component only to pass therethrough and is preferably oriented so that optimum angle of incidence i of the polarized light on, the windshield for example, for attenuation of the reflection thereof, occurs. The outer surface of the window is preferably provided with a non-reflecting or anti-glare finish so that light from a source external of the meter is not reflected off the window. The arrangement ensures that visibility obscuring reflections on the windshield and the like caused by the meter mounted in prominent position on the instrument panel is not caused by light sources within or external of the meter.
