TY - JOUR PY - 1994// TI - Light output of U.S., European, and Japanese low-beam headlamps JO - Transportation research record A1 - Sivak, Michael A1 - Flannagan, Michael J. A1 - Sato, Takashi SP - 99 EP - 111 VL - 1456 IS - N2 - The light outputs of 150 production low-beam headlamps manufactured for use in the United States, Europe, and Japan were analyzed. The information is presented in tabular form by jurisdiction for the 25th-percentile, the median (50th-percentile), and the 75th-percentile luminous intensities from 20 degrees left to 20 degrees right and from 5 degrees down to 5 degrees up. The median luminous intensities by jurisdiction are also shown in a graphical form. To illustrate the utility of these data, calculations are presented for median illuminances from U.S. low-beam headlamps falling on points in space corresponding to sample locations of rearview mirrors, traffic signs, and road delineation.
