These lights give you many long hours of usage and it will take you years to burn them out if they are used as most of us do - according to the manufacturer, these lights have a 5,000 hour bulb life. This is why I feel confident using this light bulb.

The next step is to cut and remove the bulb that was no longer working from the light fixture.

Next, test the grain of wheat bulb and then test it using a 9-volt battery to be sure it works. First wrap one wire around the positive post of the battery and do the same with the negative side of the battery. If the bulb works, it will light up, if not, try a different bulb.
