Current drain is a mere 1.35 amps and a simple two wire control scheme can be used to enable or disable the emitter using either a 12 volt source or ground. High or low priority transmission is selected via a single wire. The Microdash Preemption is built on the extremely popular Linear Microthin housing and lens design; the modular construction makes changes in the field a snap.
