I would probably create a hole for the "pilot screw" to screw in to.
Sounds like this is a safety ground, so probably not too good an idea
to ignore it (especially in a pool -- water and electricity don't play
together nicely, y'know!). Depending on what I have to work with,
some possibilities: self-tapping sheet metal screw to replace the
"pilot screw". Self-tapping screw which clamps a suitable wire to
ground, rig something to connect the lamp fixture's ground to system
The possibility still exists the replacement lamp will trip the GFCI.
I definately would _not_
bypass the GFCI; replacing the GFCI with a
more current model may be a possiblity as the old one could be old and
a little too sensitive.
