2000 Mazda 626 how do you change a headlight

You will need a philips tip screwdriver, and a 10mm socket and driver. Open hood and find the philips screw that holds in the parking lamp and remove screw. Slide parking lamp forward. It will pop out straight forward. The 2 10mm screws are behind the parking lamps. The Headlamp will now come out with locator buttons on the left side and a slide type fitting on the right. This is of course for the passenger side. Just oposite for the drivers side.
