Abstract
A lamp assembly includes a lamp base having power input terminals, a fluorescent lamp connected to the terminals through a manually operated switch that is on an exterior of the lamp base so that when power is supplied to the terminals the fluorescent lamp is selectively powered by manual operation of the switch, and a light emitting diode (LED) inseparably connected to the terminals so that when power is supplied to the terminals the LED is always powered. This arrangement allows the LED to be ON regardless of the operating status of the fluorescent lamp and allows the fluorescent lamp to be turned OFF while the LED remains ON.
