I purchased the dual brite motion sensing lights and put two of them on my garage, i wired them from a switch to either side of the door on one circuit allowing them to be individual sensors but i keep getting a very faint light all day when it should be shut off, any reason why when i put them in master/slave mode this doesn't happen but when i try keeping them seperate on the same circuit one always gives me a faint light when it is supposed to be off, i have returned the fixture three times and the first one worked for a week, the second was wrong off the start and the third one now was good for two days. Is it equipment failure or am i gonna have to wire it to dual master to make it work for what i need. The master/slave configuration is a waste of money for the second motion sensor.
