ABSTRACT:
The present invention is a waterproof indicator light, which solves the problem that the length of the space needed for the battery is too long, caused by the battery needing to be in serial connection for the conventional waterproof indicator light. The invention includes a step-up apparatus in the illuminating module to reduce the number of batteries needed, or to change to a button mercury battery that has a lower voltage and is smaller. Then, the step-up apparatus is used to increase the voltage. By so doing, it largely reduces the space needed for the battery set, increases the length of the refracting surface for the illuminating module, and increases the illuminating effect as well.
