Dear Mr. Gill: This is in reply to your letter of January 20, 1978, asking for a interpretation of the requirements in Motor Vehicle Safety Standard No. 123, *Motorcycle Controls and Displays*, for motorcycle headlamp upper-lower beam switches.; Standard No. 123 requires this control to be pushed 'up' for the uppe beam and 'down' for the lower beam. You have stated with respect to the design which you submitted that 'when the lower beam is on, the control surface is parallel to the housing. To switch to the high beam the top of the control is pushed ... to switch to the lower beam the bottom of the control is pushed.' You asked if this design is within the scope of the operation described in Standard No. 123.; It appears from your description that up and down motions of the thum operate the upper and lower beams respectively and that the design conforms to Standard No. 123's requirements.; Sincerely, Joseph J. Levin, Jr., Chief Counsel
