Locate the manual of the equipment. It is always a good idea to follow the steps within the manual. Some manuals have detailed graphics that show where the light bulb is located and how to replace it. Make sure the equipment has been off for at least 30 minutes. Some of these light bulbs burn extremely hot and can cause severe burns. When removing the light bulb, be very careful when taking it out of the socket. Some sockets are made out of ceramic and can be fragile. You may require a screwdriver to remove the illuminator in order to get to the light bulb. Compare the removed light bulb with the new bulb. There are so many different types of bulbs and manufacturers of bulbs that even the slightest change may affect the equipment. It is also a good idea to keep the burtn out light bulb for future reference.
Never touch the glass of the light bulb especially if you are replacing a mercury short arc, xenon, or halogen bulb. The oil from your skin increases the surface temperature of the bulb causing the light bulb to a have shorter life. Reverse the procedures when you removed the burnt out light bulb. Some higher end equipment require filament alignment. There should be adjustment screws that change the X and Y axis for proper performance.
