The short answer is that it's a SPAD (Signal Passed At Danger) Indicator.

snip Barry's explanation

There are others dotted around the country. I know of some at
Reading. They tend to appear in busy/cluttered areas where risk of
over run is higher (or at least, the consequences could be worse).

Thanks - I assume the most likely scenario is that the driver accepts
the RA from the platform and ignores the signal (which presumably he
will have acknowledged when approaching the platform) some minutes
before.
