Depth-compensated underwater light

An underwater light comprising:

• a rigid housing incorporating a window for permitting the passage of light therethrough;
• a flexible diaphragm sealably mounted to said rigid housing to define a void therebetween;
• a light source mounted in said void for directing light generated thereby through said window;
• a power source mounted in said void for generating electrical power;
• an open electrical circuit mounted in said void and coupling said power source to said light source, said open electrical circuit including spaced-apart terminals for preventing said electrical power from being delivered to said light source;
• one of said terminals coupled to said flexible diaphragm and aligned with another of said terminals, wherein flexing of said flexible diaphragm into said void causes said terminals to contact one another wherein said electrical power is delivered to said light source;
• and
• a non-compressible dielectric fluid filling said void.

An underwater light for mounting in an opening of a flexible housing, comprising:

• a transparent cylindrical rigid housing for permitting the passage of light therethrough, said rigid housing sized for a compression fit in said opening of said flexible housing;
• an opaque flexible diaphragm sealed to said rigid housing to define a void therebetween;
• a light source mounted to said rigid housing and in said void for directing light generated thereby through said rigid housing;
• a power source mounted to said rigid housing and in said void for generating electrical power;
• an open electrical circuit mounted in said void and coupling said power source to said light source, said open electrical circuit including spaced-apart terminals for preventing said electrical power from being delivered to said light source;
• one of said terminals coupled to said flexible diaphragm and aligned with another of said terminals, wherein flexing of said flexible diaphragm into said void causes said terminals to contact one another wherein said electrical power is delivered to said light source;
• and
• a non-compressible dielectric fluid filling said void.
