Weather insulated tip-up light mounting

In combination with a fishing rig including a substantially upright mast and a normally straight resilient strip having one end affixed near the top of said mast and another end releasably secured on said mast at a position to bow said strip, a signal apparatus comprising:

• a case having a lower cavity sized to receive the top of said mast to support said case, said case having a lateral cavity sized to receive a storage source of electrical energy;
• a pair of battery terminals mounted at opposite ends of said lateral cavity;
• an electrical light mounted atop said case;
• and
• a switch means mounted laterally upon said case opposite said lateral cavity and serially connected with said electrical light and said pair of battery terminals, said switch means having:
• a pair of electrical contacts;
• and
• a laterally projecting actuator which has biasing means biased towards said resilient strip, said actuator operating said switch means to close and open a circuit with said light and said battery terminals, said actuator being reciprocatable from a closed to an open position, said actuator being mounted to be electrically isolated from said contacts, said actuator being positioned to engage said resilient strip when it is secured in a bowed position and to open the circuit, said actuator being operable to close the circuit when said resilient strip is released to a substantially straight condition.
