Signal Dynamics Self-Canceling Turn Signal Module 01501 Perfect for custom builds or retrofitting models without self-canceling turn signals Features three turn signal timing modes: a one-second press of the turn signal button causes seven seconds of turn signal flash before self-cancel, a two-second press causes 20 seconds of flash before self-cancel and a four-second press causes 75 seconds of flash before self-cancel All flash modes can be canceled with a second push of the turn signal button Flash time is consistent whether using incandescent or LED lighting Simultaneous depression of right and left turn signal buttons for one second begins hazard mode; flash continues until manually canceled
