The Vision X Unite Series LED lightbar system cabling can be configured in a variety of ways using the different power accessories. As standard, each lightbar (straight and curved) contains enough components to configure the LED modules using a single circuit (all on or all off). Since the modules can be powered individually, the Unite bar can be configured to operate multiple circuits with the help of additional power accessories. Some examples are the use of amber flood modules on the outside and white spot modules in the centre.Among the additional elements is the high ampere power connector.This is a power jack that has a 2-pin High Amp Deutch connector on one end and a 2-pin insert on the other to connect to the module, which is used for 40" to 50" Unite LED bars .From the top menu choose the installation side.
