Mazda Turn Signal Essentials

On most car models, when the turn signal switch is moved to indicate a turn, one of the front (as well as one of the rear bulbs) is switched to the turn signal circuit. The side indicating a turn will flash while the other side will remain connected to the stop lamp circuit and will light steadily when the brakes are applied.

Turn signal circuits must have an indicator lamp or lamps to alert the driver when the signals are operating. This is also quite useful and handy to have around in order for drivers to know when there is failure in one or more bulbs.

This is basically how a Mazda Turn Signal operates. When lighting troubles occur, the problems are not so very different from headlight woes. For instance, all signal lamps and indicator lamps are inoperative when there is a blown fuse or faulty flasher, in the same manner that it stays inoperative when there is a faulty switch or connection. On the other hand, if one signal lamp or indicator lamp keeps staying on despite one's attempts to activate the other, then the other bulb in the circuit is likely to have already burned out. Or, it can also pertain to a poor ground or an open circuit.

Another likely problem is if the flashing rate is just a wee bit too quick at times. This can mean a high voltage in circuit, faulty or defective type flasher, or even something as simple as having installed the wrong kinds of bulbs. On the other side of the coin, it also becomes problematic when the flashing rate is too slow. This could point to a low voltage or high resistance in the circuit, along with faulty or even flawed type of flasher and yes, again, the use of bulbs that prove highly unsuitable for the job. If however, there is no flashing on either side when the Mazda Turn signal switch is on, then one can narrow the problem down to a wrong choice of flasher.
