Depends on the state, I suppose. Legal in Michigan.

Reference: MCL 257.696: "A motor vehicle may be equipped with not more
than 2 spot lamps, except that a motorcycle shall not be equipped with
more than 1 spot lamp, and every lighted spot lamp shall be so aimed
and used upon approaching another vehicle that no part of the beam will
be directed into the eyes of the approaching driver. Spot lamps may not
emit other than either a white or amber light."
