Is spraying deoxit on my fuse box a bad idea?

I’ve posted in the past about my headlight & running light on the sidecar intermittently not working.

I had brought it in for service for that specific problem a while ago and the shop ended up replacing one of the relays in the fuse box. That appeared to have fixed the issue. For a while.

Now the problem is happening again and I have a hard time believing that this is yet another relay gone bad. When it happens now, if I hit the cover over the fuse block, the lights come back on.

Is it possible the relay is fine and the connectors in the block are dirty? If that’s the case, is spraying Deoxit contact cleaner directly onto the block safe?

The high beam switch on the handle bars no longer does anything either.
