remote open the door but wont close it keep coming back up, but i can close it from the inside ,do you think this will solve the problem ?liftmast

If you're able to close the door by holding down the button on the wall , then yes. However, it could be bad wiring ... maybe a bad connection. I see lots of time people use electrical tape and the adhesive actually breaks the connection over time. Try resplicing the connections if they are spliced first. If there is no splice, then it's possible the eyes are bad. To test them... use a newer 9volt battery. Detach both of the sensors and connect the matching wires together. Connect the wire with the black line to the positive side and the white to the negative. Line them so they are facing each other. If both lights come on then it's not the eyes. Could be a bad wire that is pinched or a bad circuit board on the motor unit. Good luck.

do these sensors come with wires attached to them ?

3 foot pigtails. You'll need to have wire from your opener to these and then splice them.

will they work for a craftsman opener ?

Yes, I used my with a Craftsman and it worked perfect.

Could I use this sensor to light up a light when the sensor is activated?

No. it has a circuit board in the door opening. It is not working like a switch but if the light is already on the garage door opener then that light will come on
