Side marker lights Information

Turn indicators are located at the corners. In rare cases they can be located on sides. Turn indicators are designed to alert other drivers about making a turn or about merging. There is one more important condition – turn indicators must be of one amber yellow colour. Eclectic turn signals appeared little more than a century ago, in 1907. However, on all cars they have been used only 30 years later. Since those times the existence of such lighting devices became mandatory for any car.

More than fifty years ago turn indicators were always on unlike today's turn signals. Engineers mounted them slightly above the front door. But since they were quite fragile, they often break. In modern cars turn signal lever is located under the steering wheel. So, the driver can easily turn on the turn signal without removing his hand from the wheel.

After the driver completes the manoeuvre, the switch should return to its original position automatically. Frequency of light flashes should be constant in the range of 60 to 120 per minute. When the turn indicators are turned on, on the dashboard of any car lights green indicator. Also you can hear a specific sound reminding you to switch off the turn indicator.
