A lamp assembly (10) for use as a vehicle marker lamp or a vehicle clearance lamp is disclosed. A lamp assembly includes a multifaceted prismatic diffuser (12) to which a number of LEDs (14) are fitted. The diffuser has an outwardly directed portion (20), a center portion (22), and an inwardly directed portion (24). The outwardly directed portion and inwardly directed portion are both formed with angularly offset facets (26-38). The LEDs are fitted into openings (40) that are formed in the facets (32, 34) of the inwardly directed portion of the diffuser. When the LEDs are energized, the light emitted thereby is initially diffused throughout all of the diffuser. It is then emitted from the facets forming the outer portion of the diffuser such that it can be seen over a wide viewing angle.
