GLV is a display technology that uses dynamically adjustable diffraction gratings to create a display. It was invented by and licensed by Silicon Light Machines.
In a digital clock, electrical energy is transformed into light energy when the LED or LCD display lights up to show the time. The electrical energy powers the circuitry of the clock which then activates the display to emit light.
To brighten anything,light needs to reflect from that medium.Space has nothing,except some heavenly bodies.When light strikes a heavenly body, it probably brightens it.If their is nothing,how light can brighten it?
Brighten means to make lighter (in terms of light not weight). "If you open a blind you will brighten the room."
Remove the decorative cover from the face of the clock. Remove the retaining screws from the clock. The light will be in the back of the clock. Push the light in and turn at the same time to remove the light. Reverse the process to install the new light.
In a digital clock, electrical energy from the battery or power outlet is transformed into light energy in the form of the display. The clock uses electronic components to process the electrical energy and produce the output of light to show the time.

I have a 1998 Pontiac GT and the light was burned out on the display. Could not find one at the dealership. The place i found one was www.corvetteradios.com. Hope this helps. I had that problem on my GP GT ´97, I pulled out the radio and there´s a small light behind the dispaly, it was burned, I had to replace it. You can buy it in radioshack, you need to weld it.
light gates are used to brighten up the entrance when it is dark.
