My ML320 (2002) uses an standard H7 bulb.
To change the light bulb on a 1999 Mercedes ML320, first, ensure the vehicle is turned off and the keys are removed. Open the hood and locate the headlight assembly; you may need to remove the cover or clips to access the bulb. Disconnect the wiring harness from the bulb, twist the bulb counterclockwise to remove it, and then replace it with a new bulb by reversing the process. Finally, reconnect the wiring harness and test the new bulb before closing the assembly.
The highest watt headlight bulb you can use in a 2000 Mazda 323 is 65 watts. Most vehicles use a 55 watt bulb.
Just open the engine hood, and look behind either headlight that is out, and remove the cover behind the headlight, should probably be a turning cover, turn cover counter clockwise to remove, then un-plug connection for bulb, and remove light bulb. Light bulb will probably be held in by 2 metal spring clips, that are hooked in, just un-hook springs to remove bulb.
