As you're modelling BR it should be a banner, light repeaters were an LU thing.....and at the other end of the layout @Boyblunder has been testing the possibility of advanced repeaters for the up home signal, lights in this case.

or a banner type here. This would require a servo to operate it.

Easier to do in 7mm than 4mm?I’d vote for the banner….
(but I don’t have to make it!)

We think that drivers on through trains would not be able to see the home starter until they come out under the station building, below is not quite the drivers view but you can see that the signal would be obscured from further back as you enter the station.Is a repeater actually required in this location? Or will locos be stopping before the station building bridge?
Would not the up home and distant signal (protecting the platform) convey the status of the up starter signal at the other end of the platform?

I'm sure I've seen photos of very short semaphore signals such the the arm could be seen under your bridge, possibly as a repeater arm below the normal one?

Sorry for the wrong terminology.

"OFF" indicators are/were for showing platform staff and guards that the platform starter signal was showing a proceed aspect, thus avoiding "ding-ding and away" SPADs. They were not officially for drivers use.

I think this was the original idea using the light shown in post # 1,300. Agreed that the banner will be the wrong application in this position."OFF" indicators are/were for showing platform staff and guards that the platform starter signal was showing a proceed aspect, thus avoiding "ding-ding and away" SPADs.

Probably worth mentioning that we are installing searchlight signals rather than semaphore. This area of NE London, only 12 miles from Liverpool Street, seems to have received this change by our era.
