Solid build quality and works perfectly

The detector responds to covering the lens immediately, so that it can be tested after installation even in daylight through simple cases sealing the optics equal.
When the lights go on, a delay of about 1 minute is installed (perhaps a little shorter). That's perfect, because he thus from a passing car, can be explained by short light eg no mistake and the connected lamp does not go out immediately.
For my purposes perfectly adequate.
He turned a spotlight in front of the garage, which is parallel to the lamp in the garage door opener that always concerns when opening and closing, and about 2 minutes stopping time has to burn. Since the headlamp is to turn the outside only in the dark, the lamp relay activates the door opener that attracts, while the lamp is on. The phase, which is then turned on, comes from the brightness detector, so that the headlamp halt burns only when it is dark.
