Electric system auto parts: Indicator Relay / Flasher Unit

Turn indicator relay interrupter is the component part of the turn indicator system. It provides turn indicators’ lamp blinking with a defined frequency. Turn indicator relay interrupter consists of a switch and a pulse generator. And there is possibility of work in two modes: in mode of fault signalling and in mode of turn indicating. There are used the following types of turn indicator interrupters: thermal, bimetallic, digital and electronic. In new cars often there is no necessity in a separate turn indicator interrupter, because its function is performed by a control block.

Turn indicator interrupter is designed in such a way that it is possible to warn about turn indicator lamps’ faultiness. If the lamp is faulty, then a minor current flows and the frequency of blinking doubles. If the turn indicators do not switch off, then the turn indicator relay interrupter is broken down. For the same reason lamps of turn indicators may not light up. In this case one more reason may be burned-out protecting device. The situation when all the lamps fuse at the same time is also possible. If a wrong lamp is fixed, then the frequency of blinking will differ from the usual one. Lamps and turn indicator relay interrupter must correspond to the car model. Otherwise there is no guarantee that they will function in the right way. You will ascertain this immediately after installation.

Turn indicator interrupter’s substitution is not difficult. But in many cars turn indicator interrupter is situated quite inconveniently, and to get it you need to disassemble other details. If you are not sure that you can do this without assistance, it is better to address to a service centre. Do you search any parts? Then consult our car parts Internet shop.

It is necessary to check the part immediately in case if any malfunctions signs appeared.
