ELECTRONIC FLASHER 2 TERMINAL 35A

This is an electronic turn signal and hazard flasher relay for heavy-duty trucks and buses. It controls the flashing of up to 16 lamps (2 to 35 amp load) on a 12-volt DC electrical system, ensuring a steady flash rate without hyper-flashing. The unit is typically replaced when lights stay on, flash too fast, or stop flashing entirely due to a failed mechanical or electronic flasher. Its solid-state design is more durable than thermal flashers and meets SAE 100-hour reliability standards for demanding commercial environments.
