A warning system is provided, comprising: a warning signal source (12); a piezo-electric transducer (32) deformable by a user; a rechargeable battery (26), connected to receive an electric current generated due to deformation of the piezo-electric transducer (32) to charge the battery (26); and a controller (22) arranged to sense receipt of an electric current from the piezo-electric transducer (32), indicative of the presence of a user, and to trigger activation of the warning signal source (12). In this way, the system is able to use the piezo-electric transducers (32) both as a source of electric current to charge the battery (26) and as a detector of the presence of a user for triggering activation of the warning signal source (12). A solar panel (30) may also be provided both to charge the battery (26) and to enable detection by the controller (22) of ambient light levels. Activation of the warning signal source (12) may be disabled by the controller (22) during higher ambient light levels.
