Abstract
A battery-powered remote control for radiating wireless signals to control a controlled device has a night light that glows whereby it is visible in a darkened room and the battery lasts at least about three years. It also includes a wireless transmitter, a controller, a battery and a control element. The control element generates a signal when activated to cause the controller to operate the wireless transmitter to transmit a wireless signal to control the controlled device. The night light comprises a light emitting diode and a light pipe having a textured front surface. A power supply circuit for the LED provides an LED current from the battery. The LED has a normal operating current range and the LED current is several orders of magnitude below the normal operating current range.
