An integrated LED warning and vehicle lamp has a base configured to replace an existing vehicle lamp by reception into the lamp's reflector shell. The integrated warning and vehicle lamp includes first and second arrays of LEDs arranged on a support projecting from the base. One array is used to reproduce the vehicle signal and the second array provides a warning light signal. A collimator organizes light from one or more LED in a direction aligned with the intended direction of light emission from the vehicle lamp. An interface electrical circuit connects one array of LEDs to the vehicle electrical system. A warning signal electrical circuit energizes the other array to produce a variety of warning signals and/or illumination patterns.
