  • Poor / loose connections

    When the circuit is not complete as it ought to be, chances are the excessive electricity will create more of an ‘arc’ and this means the electricity will not flow smoothly. There will be excessive heat produced in the fitting and eventually it will blow.

    When the connection within the spring is loose, the electricity will ‘arc’ around the contact and this will eventually lead to excessive emission of heat and lead to bowing as well. Well, you can identify this problem by simply checking on the contact and see whether it looks pitted.

This usually happens when the bulbs get in touch with water or moisture that has leaked within. Once this happens, the bulb will get damaged. On this note, you should ensure the bulb has been well installed so that the filament remains secure.

Check the electrical system of the car

During the installation process, always ensure that the electrical connectors that emanate from the power source have been well joined within the metal connectors to the headlight bulbs, the alternator on the other hand should be monitored to ensure there is no overcharging of the battery. Ideally, the recommended voltage for the bulb is usually 13.2 volts.

Good quality Bulbs

In most cases, users can be tempted to go for the cheap quality kind of bulbs. However, they are not the best since they lack quality components that usually give them a short life span. High quality bulbs are those which have to go through a series of testing and the required quality standards.
