Four automotive lighting components were tested in three commercial testing laboratories to estimate the degree of photometric data repeatability and reproducibility. The laboratories used the photometric testing techniques required by Federal Motor Vehicle Safety Standard No. 108. The precision of this test method was placed in a range of about 10 percent coefficient of variation. However, this value should be considered more as an indication of existing conditions than as a predictive parameter.
