Consequently, no inspections are made for illumination.

In the case of urgent faults in signal equipment, acceptable operation should be restored within eight hours and a full repair effected within 7 consecutive days.

In the case of non urgent faults in signal equipment, a full repair should be effected within seven consecutive days.

In the case of optical equipment, red lamp failures should be repaired within six hours. Other lamp failures, push button units and lantern bodies should be repaired within twelve hours. Backing boards, white strips and visors will be repaired within twenty four hours.

Three monthly inspection of equipment are carried out in accordance with HD 24/86.

Bulk lamps changes will be as follows:

Vehicle reds and greens	Every 6 months
Pedestrian reds and greens
All other lamp (including ambers)	Every 12 months

External cleaning of all lantern aspects, photo electric cells and box signs is carried out every six months.
