4-Piece 20-LED Manual-Switch Strobe Light Kit

The aluminum heads, shared controller and eighteen manually selected modes form a complete 12 V warning system for distributed mounting. I-BS-M4-20 uses twenty LEDs in each of four elongated lightheads, creating the longest optical face in the manual M4 kit group.

Choose it when the installation has room for the long heads and the 40 W configuration is the intended bill-of-materials entry. Lock the switch position, controller location, cable routes and selected color variant together so the four heads remain one coordinated installation.
