Light Tripping GFCI

[KurtV]

The GFCI outlet trips whenever I energize my negative edge trough light.

The lens on this light was cracked over the winter and the light filled with water. To remedy this, I replaced the lens, the lamp, and the gasket but the light still trips the GFCI. The light does not have any water in it. Any ideas on the cause?

Even condensation can be enough water to cause the GFCI to trip, so it can be tough to get something dry enough to keep it from tripping. Doubly so in a closed environment like inside the light.
