This economical dual-bulb rain light offers redundancy: Even if one bulb burns out, the other will still work. No worries about getting a black flag for a burned-out rain light while leading a race!
The single-wire design requires one of the mounting bolts to be grounded. A drain hole is provided in the bottom of the red plastic lens, so the light must be mounted with the power wire pointing downwards. Measures approximately 4 inches wide by 2 inches high. A rubberized gasket is provided to help provide some isolation from vibration. Includes 2 common #193 wedge-base automotive bulbs.
