TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of September 22 asking for clarification of the requirement for spacing of rear identification lamps on trailers, as applicable to your "change number 21-23."

Until January 1, 1972, Table II of Federal Motor Vehicle Safety Standard No. 108 requires that the three-lamp cluster be mounted "as close as practicable to the vertical center line." However, beginning January 1, 1972, the center lamp of the three-lamp cluster must be mounted on the vertical center line, and the offset arrangement in change number 21-23 will no longer meet the requirements of Standard No. 108.
