Rgb leds for a tachometer light array

Abstract

The presented invention is a low profile light bar tachometer display which includes a plurality of RGB LEDs or similar RGB color model light-emitting devices organized and arrayed in a segmented, flexible tachometer case that can be manipulated and contoured to conform to the top of the dash assembly of an automobile or any surface deemed suitable for the needs of the driver of an automobile. The lights provide a highly visible, illuminated, color changing display, so the driver can immediately assess the engine's RPM, power band, redline, or maximum torque from the change in light color or light position. The light array provides a repeatable, reliable and adjustable indication of the usable range of the engine's rpm, but does not indicate actual rpm.

What is claimed is: 
     
         1 . A light source for displaying the rpm of an engine comprising a plurality of RGB light emitting devices. 
     
     
         2 . A plurality of RGB light emitting devices, as a means for a color changing light source, for displaying the rpm of an engine. 
     
     
         3 . A plurality of RGB light emitting devices for displaying the rpm of an engine, arranged in an array wherein one or more RGB light emitting devices sequentially and or progressively illuminate across the array, initially emitting a selected color, and to the extent that the RGB light emitting devices have progressively illuminated across the array, all or some of the RGB light emitting devices that are illuminated, change and emit a different color.
