Glad you found an answer to your marathon question.
Sorry that you feel slighted by the responses you received, but it is easier to answer a concise and specific question without all the extraneous details.
Case in point:
"The location for the new bridge will be very visible. I don’t want anything too big as we’re talking a run of sockets which already struggle to accommodate TV, DVD and a Sky Q box. I also don’t want anything with very conspicuous flashing lights. Current bridge ceaselessly flashes blue and green but is at least hidden from view via Blu Tac down the side of my Hutter rack.
Two reasons re: the flashing lights. Firstly, Mrs. H. will complain if there is something constantly flashing away conspicuously whilst trying to relax, watch TV or listening to music. Secondly, one of my eye conditions means my vision will be constantly drawn to said flashing lights."
