Front marker lights

[cootuk]

1996 7.5te horsebox (I know).
For the mot, do these require front marker lights above the cab?
If not a requirement, would temoving the bulbs constitute not being fitted?
If required, does a lens cover have to be CE type approved?

Reason for asking - some kind person is in the habit of smashing the white lens covers on ours.

Yes they are required on post 1991 vehicles.
