A brake light control module for activating brake lights of a vehicle in response to activation of an engine brake of said vehicle. A control circuit of the module features a thyristor, a power lead and service lead for connection to the vehicle's electrical system and brake light service line across the thyristor, and a trigger lead for connection between the thyristor's gate terminal and an engine brake activation line of the vehicle to switch the thyristor to its conductive state when the engine brake activation line is energized. A delay circuit is installed in the power lead to prevent energization of the service lead in the event of a momentary gate signal indicative of an engine brake assisted gear shift. An operational indicator mounted within the housing is activated when the engine brake activation line is energized, thus confirming proper installation of the module.
