Thank you all for your input. I've already got some bridge rectifiers
on order from Mouser, but if none of them fit the task, I'll try four
separate diodes (or two dual diodes) instead.

Sent some gear for EMC testing.
The leds illuminated in one of the RF immunity tests.

Although I never tried it I guess they would illuminate whichever way round
they were (not) connected.
