Vintage, anti-theft cycle lamps from 1994. The three-position switch (Open, On and Off) is a key. When the key is removed, the screws in the mounting bracket are blocked by the lamp and cannot be accessed. In the Open position, the lamps slide off their mountings and can be carried away. The lamps come with two sets of keys.
