Looking opinions from others that have this sight light. Maybe I got a "lemon", but after 2 shoots it has died. Not the batteries - something appears to be broke. I can simply open the battery compartment, close it and the light might come on. But a very light thumb to the sight and it goes off and will not come back on until I repeat the process. The same is true "without" the thump - slowly turn the rheostat until it comes on, turn it a bit more to make it go off and it will not come back on until I open the battery compartment again and repeat the whole process.
