I’d say you’ve got a broken or high resistance earth that is causing that. That would be the first thing I’d check, test and visually inspect the wiring and connectors on the back of the clocks and in the engine bay especially around the battery area, main fuse box and earth points.

Check the duel brake / sidelight bulbs at rear if contacts are incorrect they short out and cause problems , on my 4x4 they turn the 4x4 off
