Auto headlight issues

[T5.1DRM]

Iv recently installed the auto headlight module to my t5.1, battery went flat this afternoon and when I open the door it beeps as if Iv left the lights on. Any ideas what the problem is? Any help will be greatly appreciated

Thanks in Advance

its suppsoded to beep tells you the lights are on, but they stay on for a certain duration that you set them up by turning the light switch when you fitted the gear
