I’m considering replacing my stock 35w fog lights with a couple h3 55w halogens as has been described on the forum. Is that too much load for the wiring, or is it within the margin of error?

1 watt = 1 volt amp. Your current will therefore increase by 57 %. The fuse will probably blow before the wiring is damaged. The fuses are supposed to protect the wiring & not the loads. Don't use a larger fuse until you run a heavier gauge wire. This assumes that the fog lights are on their own circuit with its own fuse.
