Tridon Flasher units are designed to control the flash rate of vehicle directional indicators; this is achieved by providing regular interruption of the electric current in the indicator circuit. There are 3 common styles of flasher units; electro-mechanical and electronic and thermal. Tridon offers an extensive range of flasher units in load sensitive and non load sensitive types. Electronic flasher units are load sensitive, whereby if a bulb failure occurs the flasher rate increases to indicate the failure. The flasher unit must be compatible with the vehicle electrical system; the Tridon flasher unit range has been carefully researched and engineered to suit each specific application
