Spot light bulb change

Hi all
My defender has a set of genuine Landy spotlights on it, like the ones in the pic. Before I butcher them can anyone tell me if they come part to change the bulbs in them?
Thanks.

B***ocks Cant get pics to upload. They’re the Land Rover 8” ones with plastic grids on them.
Thanks.

Woohoo. Got it now. This kind. (stole photo from the Bay)

Thanks for that. Going to give it a go then.
