As a safety precaution, make sure that the car has had time to cool down properly before starting the installation process.

Put the vehicle into park or make sure it is securely in gear.

Make sure to have the ignition turned off and the keys removed.

Be careful to avoid burns, especially when turning on or off the vehicles lighting.

Be careful to avoid crushing or cutting the bulbs. Also make sure to not touch the bulbs with your fingers, as this will cause blotting.

Fully examine the connection of the contact points, ports and the wires as faulty connections can cause lighting problems.

Make certain that the end of the bulb does not come in contact with the interior light shield of the headlight when adjusting the bulb.

Please install car headlight dust cover to ensure the normal operation of the lamp (to prevent dust and small ribbons to reduce the chances of bulb cooling fan broken to ensure the normal operation of the cooling system)
