Abstract
The invention provides for exchanging a complete luminous unit () instead of exchanging the individual components such as a battery (). For this purpose, at least one energy-saving light-emitting diode () as luminous means, a battery () and a magnetically actuable reed contact () serving as switching element are combined as luminous unit (). The use of a cost-effective light-emitting diode () and a battery () formed in space-saving fashion in accordance with the low power demand of the light-emitting diode () permits a compact configuration of the luminous unit (). The fact that the luminous unit () can be inserted into the floating body () as a unit and can be exchanged as a unit obviates a complicated battery change or change of luminous means entailing the risk of leaks.
