TITLE: FMVSS INTERPRETATION
TEXT: This is in reply to your letter of July 30, 1971, to Mr. Ed. Leysath of this office concerning the mounting location of side marker and taillights on your boat trailers.
The mounting requirements for lamps and reflectors are specified in Federal Motor Vehicle Safety Standard No. 108 (copy enclosed). It appears as if devices mounted as indicated on your drawing would meet the requirements. If, however, severe problems would be encountered in mounting the devices as indicated or the devices would be subjected to damage during normal use, other mountings may be appropriate and still meet the "as far apart as practicable" or "as far to the rear as practicable" or "as far to the front as practicable" requirements.
If water damage is the only problem when lamps and reflectors are mounted in the indicated positions, special waterproof devices are available and could be used.
