Indicator bulb for Auto

Turn indicator bulbs: operation features

Turn indicator bulbs are one of the most important light signalling devices that warn about the driver’s intention to manoeuvre. In some cases, they can be used to warn about the car breakdown and its incapability to be driven further. They have a direct impact on the road safety. In modern cars, turn indicators are fitted with filament bulbs - conventional or halogen.

Tips on how to choose, use and replace them

• On average, the service life of these devices lasts for about 250-500 hours. However, you should know that only high-quality products can work for so long. Besides, there are items with extended service life. They can work for up to 1,500 hours.
• Make sure that parameters of the bulbs you are going to buy - such as the base type - comply with your car’s standard equipment. Consider the fact that turn indicator repeaters are often fitted with baseless bulbs.
• For lights with white lenses, you should buy turn indicator bulbs with an orange shell, and vice versa.
• It is forbidden to install LED bulbs instead of standard filament ones. Firstly, most of these products are not accordingly certified, and for using them you might be punished by a fine. Secondly, due to the possible non-compliance of the component specification to the parameters of the relay, the blinking interval might be affected.

Malfunctions of turn indicator bulbs, their causes and symptoms

• Filament burnout. This malfunction can be the result of voltage changes in the electrical system, tungsten burnout, a faulty flasher relay. An inactive corresponding dashboard warning light as well as the absence of sound signal when the turn indicator light is switched on are symptoms of the failure.
• Broken circuit. Due to bad contact in the base or inside the bulb, the latter might not switch on at all or operate erratically. The problem, as a rule, is caused by the oxidation of the terminals inside the base or poor quality of the component.
• Mechanical damage of the bulb. Most often they are damaged in collisions.
