Whether your headlights are acrylic or glass, the built-in cleaning system is designed to prolong their life and make it easier for you to drive in testing conditions. They operate by automatically spraying cleaning solution on the headlights and rubbing the dirt off with a motorised brush. With an increasing reliance on technology comes the possibility for certain features to go faulty in your car, especially if they endure heavy use. The headlight cleaning system is one such feature that needs to be monitored when it comes to optimising your ability to drive well and one that should be installed by a specialist mechanic when it comes to replacing it.
