Each light is installed for nighttime driving visibility, to inform the driver of the surroundings and to ensure safety. Some lights are used for lighting the interior.

• Lights deteriorate with use, and the filament burns out.
• If the turn signal light bulbs burn out, it becomes dangerous to change lanes or turn left or right.
• If a brake light bulb is burnt out, there is danger of a rear-end collision

• When one of the pair of light bulbs is blown, it is recommended to also replace the other at the same time because the other bulb is also approaching the end of its service life
• Use the proper bulb because bulbs vary by wattage and by the place where they are used

• When scratches are created on the rubber inserts by the fine sand or dust particles that adhere to the windshield, they leave wiping lines on the windshield

If the fluid is only water, the washer fluid freezes when the air temperature reaches below 0 degree Celcius.

Even if washer fluid is added, it freezes when the temperature is lower than its freezing point. Therefore use the proper washer fluid and the proper concentration for each climate
