A G8 base halogen bulb uses two large pins to connect to its socket instead of a traditional "screw-in" pin. A variety of common items use G8 base bulbs, including such small appliances as microwaves and such items as specialty light fixtures. The process of installing a G8 base bulb is the same regardless of the application; however, the procedure to access the bulb mount may vary slightly.
Things You'll Need
Replacement G8 bulb
Inspect the appliance or light fixture to determine whether you'll need any tools to remove the bulb access panel. Gather the appropriate tools as necessary.
Unplug and power off the appliance. If you are replacing the bulb in a light fixture, be sure to turn off the light switch. Remove the access panel to the burnt-out G8 bulb.
Remove the old bulb by grasping it and gently pulling it straight out. Do not twist or turn the G8 bulb; its pins simply slide in and out.
Put on clean gloves or wrap the new G8 bulb in a paper towel or napkin. It's important not to touch halogen bulbs--this may damage them.
Insert the new G8 bulb straight into the mount. Replace the access panel. Power the appliance or device back on.
