A vehicle instrument panel assembly (12) configured to verify that light sources (26) of the assembly (12) are operating properly is provided. The assembly (12) includes a first light source (26), a second light source (28), a light detector (32), and a controller (34). The first light source (26) is operable to emit light having a first modulation (36). The second light source (28) is operable to emit light having a second modulation (38) distinguishable from the first modulation (36). The light detector (32) is configured to detect light emitted by the first light source (26) and the second light source (28). The controller (34) is configured to receive a detection signal from the light detector (32) effective for the controller (34) to determine if the first light source (26) and the second light source (28) are operating properly.
