When it's time to change the car lights?

Every driver knows that the new lamps will always shine better than the old. For example, conventional halogen lamps They have a service life of approximately 500 hours. they lose brightness and shine much weaker than the end of life. This is due to the fact that the bulb begins to darken, absorbing the light output. Therefore, the lamp is recommended to change the time, then the problems with the lighting you will not.

Please note that the lamp only changed in pairs. Otherwise, you run the risk of not even light when a lamp shines brightly, and the second is much weaker. It is also strictly prohibited to use lamps with a power much higher than the recommended by the vehicle manufacturer. This can lead to the fact that the headlights will dazzle oncoming cars, and lights with these bulbs can quickly fail because they do not cope with the increased load.

When replacing bulbs they can be kept exclusively for the cap, touch the surface of the glass can not. Remember this, because fatty traces may negatively affect the future work, the lamp can quickly break down.
