Travelling on MML (Midland Main Line) last week noticed on passing Thameslink trains a spotlight on the roof next to the pantograph.Anyone know what it's for?

It is for illuminating the pantograph well & pantograph/overhead line interface so that they can be monitored by onboard cameras. Unlike some other Dual Voltage units (which only have the camera on when the pantograph is raised) the ones on the 700 are always on so that they can monitor if things fall into the pantograph well when on third rail areas, to try and avoid repeats of the Kentish Town incident |

Cl379s also have this, I imagine most modern stock do now.
