Abstract: An automatic luminous device whose use does not require an external manual switch, which is substituted by another internal automatic switch, which activates the device only when it is placed on a sufficiently dense metal surface, nor does it require a connecting cable to an external power source, which is replaced by a preferably rechargeable battery. It was designed as an emergency light for police vehicles, and as a back-up light and is fitted with a base or casing (1) and a translucent shade (2), which, when coupled together, form a single body. Externally, the base of the casing (1) is fitted with two or more permanent magnets (3) in order to block the said casing (1), when it is placed on a sufficiently dense metal platform (4).
