LED-illuminated stop/tail lamp assembly

A lamp assembly comprising:

• a housing:
• an LED board assembly having a plurality of LEDs mounted thereon, said LED board assembly being mounted within said housing;
• a current regulating assembly having a single circuit which provides one of a high current level and a low current level mounted within said housing and on a wall of said housing so as to be positioned between said LED board assembly and said wall, said current regulating assembly being attached to a power source for providing current to the LEDs mounted on the LED board assembly, wherein said current regulating assembly provides constant current to the LEDs independent of voltage variation of the power source so as to prevent overheating of the LEDs at high supply voltages and insufficient illumination at low supply voltages, said plurality of LEDs including a first group of LEDs providing a nearly constant illumination level at both the high and low current levels and a second group of LEDs providing a substantially increased illumination level in response to the high current level, and wherein said current regulating assembly comprises a first output which provides current to said plurality of LEDs in either the low current level for a tail light mode or the high current level for a brake light mode, and a second output which provides a return path for the current to the current regulating assembly;
• and
• a lens mounted on an opening of said housing to enclose said housing and distribute light emitted from the LEDs.
