We claim the ornamental design for a light visor for sequencing instrument, as shown and described.
FIG. 1 is a front perspective view of the light visor for sequencing instrument comprising our new design;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a right side elevational view thereof; and,
FIG. 4 is a top plan view thereof.
The left side elevational view of the design shown in FIG. 1 is identical to FIG. 3.
The broken lines shown in the drawings illustrate portions of the light visor for sequencing instrument that form no part of the claimed design. The oblique shade lines indicate a translucent surface.
