Hello Valued Customer, thank you for providing your feedback and letting us know about the issue. This is certainly something that we did not expect to occur, and we are sorry for the inconvenience. The light can be adjusted to stay on anywhere from 15 seconds - 30 minutes after motion has been detected. If your lights are not staying on for the amount of time that you specify, then there appears to be an issue. Please give us a call between the hours of 7 AM – 8 PM Central Standard Time, Monday thru Friday at 1-800-654-8483, press option 4, and provide our Consumer Care Team with your personal ticket number 551805, so that we can resolve your issue promptly. Thank you and have a great day!
