This report summarizes an effort to carry out and evaluate a draft test procedure for confirming amber rear turn signal lamp color. The procedure adapts existing test procedures from Federal Motor Vehicle Safety Standard (FMVSS) No. 108, Lamps, reflective devices, and associated equipment, to accommodate testing the lamps as installed on the vehicle. The draft laboratory test procedure consists of measuring the color of the emitted light using a colorimeter and an adaptation of the tristimulus method and chromaticity coordinates as described in FMVSS No. 108. Four vehicles were subjected to the draft test procedure. Two vehicles were confirmed to have amber rear turn signal lamps, one was confirmed to be red, and the fourth was determined to be a color other than amber or red. Overall, the test procedure was found to be easy to carry out and effective in determining turn signal lamp color.
