First Claim
1. A light bar comprising:
- a plurality of modules;
a control circuit including one power supply circuit for selectively energizing each of the modules; and
wherein each of said modules comprises;
a strobe lamp curved about an axis having an anode and a cathode for energizing the strobe lamp and having a trigger for firing the strobe lamp;
a reflector positioned adjacent the strobe lamp to reflect light emitted by the strobe lamp; and
a circuit including a capacitor connected to the anode and the cathode for energizing the strobe lamp, said circuit connecting the capacitor and the trigger to the control circuit; and

Abstract
A light bar comprises a plurality of modules and a control circuit including a power supply for selectively energizing each of the modules. Each module includes a strobe lamp having an anode and a cathode for energizing the strobe lamp and having a trigger for firing the strobe lamp, a reflector positioned adjacent the strobe lamp to reflect light emitted by the strobe lamp and a circuit including a capacitor connected to the anode and the cathode for energizing the strobe lamp. The circuit of the module connects the capacitor and the trigger to the control circuit. An incandescent lamp or a high intensity discharge lamp may be used separately or in combination with the strobe. Multicolor operation or the use of LCD panels as filters or reflectors is also contemplated.
