A modular light bar having crisscross lighting in the front and rear. Each module may include two horizontal layers of lighting supported on supports connected to a longitudinal base. A wire harness is positioned within a longitudinal channel in the longitudinal base, with the harness having one end connected to quick disconnects within the modules and having another end connected to a controller. Each of the light bar module is serviceable independent of the other light bar modules, such that the support positioned within and connected to the light bar module being serviced is removable from the light bar module without accessing the other light bar modules by disconnecting the quick disconnect positioned within each light bar module being serviced.
