GFI Problem

When I turn on the light in my garage the GFI in the garage trips. However the light does come on. Any ideas on what the problem might be, and what I can do to further research the problem?

The GFCI is miswired.
First thing to do is open the GFCI and see how it is wired. Then determine how the light is wired into the circuit.

It sounds like the light is not wired into the load side of the GFCI meaning the light is not GFCI protected.

Has anything changed recently? New lighting fixture or wiring changes?

This has just started. The light switch has been working fine since we moved in, 6 years ago. Nothing has changed. No new lighting fixtures or wiring changes.Could the light switch or the GFI outlet go bad?

Those are always possibilities. The light and switch really shouldn't be GFCI protected, but it isn't a code violation for them to be. Hard to diagnose with out being there, but my first reaction is that the GFCI is bad. Is it a GFCI breaker or receptacle?

Since the light still goes on, the GFI definitely isn't working the way it should be.
If it's a normal incandescent bulb, there's not much to go wrong with it. If it's a CFL or LED, it's possible it's causing some noise on the line that's confusing the GFI. Weird things like that have happened before.

If it's a CFL or LED bulb, I would temporarily replace it with a standard bulb and see if it still happens.

If so, I would probably try replacing the GFI. In either case, it's probably an over-sensitive (old) GFI receptacle that's the root of the problem.

I have ordered a new GFCI from Amazon, it will be here on Tuesday. I will update after I install it. I will also try replacing the CFL bulb first.

It was the light bulb. When I went to unscrew it, it broke off at the base. When I put a new one it everything worked. Thanks everyone for your help and suggestions.
