Does anyone have a good source for a 24 volt DC flashing red led panel mount indicator light

it must be vandal and liquid proof to some degree

Thanks for looking

 

A "blinking" red LED http://www.radioshack.com/product/index.jsp?productId=2062553 with the appropriate series resistor...2.2KΩ/0.5W Many waterproof LED mounts out there. How vandal proof? Would covering it up with a wad of chewing gum constitute a failure?
