A combination lamp for use in a vehicle includes a number of reflector modules, with each reflector module including a reflector, a first light emitting diode (“LED”) positioned at a focus of the reflector, and a second LED offset from the focus of the reflector. The lamp may also include another reflector module having a reflector and a single, common LED positioned at a focus of the reflector. When the first LEDs and the common LED are energized, the combination lamp produces a first light pattern. When the second LEDs and the common LED are energized, the combination lamp produces a second light pattern. The first light pattern may be a fog lamp light pattern, and the second light pattern may be a daytime running lamp light pattern. The combination lamp may include four, five, or more reflector modules, including the one reflector module having the single, common LED.
