Dear Mr. Burgess: This responds to your February 4, 1977, question whether Safet Standard No. 116, *Motor Vehicle Brake Fluids*, permits DOT 3 and DOT 4 brake fluids to be colored 'fluorescent yellow.'; The answer to your question is yes. paragraph S5.1.14 of Standard No 116 specified that DOT 3 and DOT 4 fluids manufactured on or after September 1, 1978, shall be 'colorless to amber.' The agency interprets this color range to include any 'yellow,' whether or not fluorescent. Although not required, we consider fluorescence to be an added safety factor since it would facilitate the detection of leaks in the braking system.; Sincerely, Frank A. Berndt, Acting Chief Counsel
