* If you are not comfortable working on your own car, you can have a professional mechanic replace the headlight lens for you.
* When you are removing the old headlight lens, be careful not to break the lens. If the lens breaks, you will need to replace the entire headlight assembly.
* When you are installing the new headlight lens, make sure that it is seated properly in the assembly. If the lens is not seated properly, it could cause problems with the headlight beam.
