This has a mirror to one side & reverse is fitted with 8 small orange reflectors (for night use) & a central “flap” that springs up & has a red reflector on the bottom side. This reflector is visible through a gap in the “silvering” on the front of the mirror. There are instructions for use printed on the bottom of both lid sections. With attached cord lanyard. A bit grubby & would have had a band of sticky tape around it to hold it all together but in good used condition overall. Stock code M12442.
