Lights and reflectors are covered by different rules. In California at
least, the only regulations on reflective material are:
--------------------------------------------------------------
 Use of Reflectorizing Material

25500. (a) Area reflectorizing material may be displayed on any vehicle,
provided: the color red is not displayed on the front; designs do not tend
to distort the length or width of the vehicle; and designs do not resemble
official traffic control devices, except that alternate striping resembling
a barricade pattern may be used.

No vehicle shall be equipped with area reflectorizing material contrary to
these provisions.

I can't imagine other states are that far different
