LMT Mercer created this Solar Splitter to make LED Solar light installation easier than ever. One Solar Collecting Post Cap can power two lights with this splitter, and keep in mind that the splitter will cause the brightness of each light to decrease by half. Be sure to firmly connect each fitting (a gap should not be visible between the connector ends). Please note: this harness is for use when connecting a Solar Collecting Post Cap to a solar post stair, or under rail light only. Not for use with low voltage lighting.
