An illumination device for mounting inside a balloon comprises a housing 10 in which are mounted a light source, such as LED 20, and a battery power source for the light source. The battery may comprise button cells 31 & 32 mounted in chamber 11. The housing 10 is formed of plastics material and may be formed by two mating sections 10A, 10B which are hingedly connected to each other. Further, this housing 10 includes an integrally formed spring element portion 25 which is arranged to bias connector members 22, 24 of the light source 20 and the battery power source into contact with each other. This speeds production and provides a reliable device. An insulating strip / pull tab 40 extends out of the housing. When the strip is pulled, the LED is connected to the batteries and lights up.
