Abstract
A light string power module is provided for providing power to light strings while replicating a lighting pattern from a first light string in providing said power. The illumination pattern of the first light string, which is not powered by the light string power module, is detected by examining the voltage polarities presented on the leads of a first connector to which the first light string is attached. These detected polarities are replicated by a switching module at matching leads on a second connector to which a second light string is attached. A power processing module accepts input power and provides output DC power to the switching module such that the second light string is powered by said output DC power in concert with the replicated voltage polarities so as to replicate the light pattern presented by the first light string on the second light string.
