No question I like to take my time! Okay, Three hours is divided into mechanical installation, with a little of alignlent in between. Wiring CORRECTLY,,,,, solidering, cutting to fit the four pin connectors to fit the six pins, arranging the connectors in correct order.. Then,, installing the vacuum hoses and regulator dial for the headlamp actuation....... Yep,, 3 hours sounds about right! If you count the HID installation,, make it five hours. They look great and (most importantly) work great after all the work.
