There is some debate as to whether the 1041 models shown here or the 245 model which is just slightly different are more accurate. Most people find the difference to be slight enough to not matter. These indicators were used for the slo-blo light and flashing indicator beside the vent on the thrower as well as an indicator on the trap pedal.
