A sealed housing for electronic or electrical equipment has a clamping plate sealed by a resilient seal to a main case portion and an outer plate or trim member to cover the heads of the fixing screws. The trim member has protruding from its underside fixing pins which are gripped by resilient blind sockets sealed into the clamping plate. The clamping plate is partly formed of transparent material so that dials etc. can be seen. Edge-illumination of the transparent portion of the clamping plate is provided by lamp bulbs mounted in sockets sealed into the clamping plate. The lamp bulbs, hidden by the trim member, lie in apertures in the transparent portion, thus bulb replacement can be effected without opening the sealed housing.
