Those photos were probably taken in the 1990s, before the MA60s were changed for ZX3s in 2000.

The GEC Bricks on the M3W to M25N approach ramp have been relamped within the last week (or the installations were repaired).

It appears that the M25 now has part night lighting on its NW section - north of J16 for the M40.

The following are all dash cam images.

Sign at J16 for the M40.

Sign at J17 on the SB on slip.

The roundabout under J17 still has one GEC brick on it which has been missed by the Hertfordshire LED retrofit. The M25 overbridges have recessed lights set into the bridge beams, whilst some of these are SON, there are a number which are still SOX and still working.

Between J16 and J17 a new maintenance access slip has been built. These slips roads and the main carriageway lighting are now lit by LED.

Image

Returning home, the lighting on this section of the M25, is in a poor state of repair. There are large sections not working at all and many other where lamps are out. I suspect the lamps are at end of life - with no re-lamping since this section was widened and the lighting installed.

More likely is that the wiring used on the 2009 widening projects was rather poor quality and parts of it have failed, leaving large batches of columns out of action. Presumably this is either too expensive to sort out or the contractor simply can't be bothered.

Last year, several columns at J21 sporting MA60s (particularly on the M25E to M1N flyover) were removed, presumably because their steel foundations had failed structural testing due to corrosion. They are still missing and one can wonder whether they will ever be replaced.

Highways England have chronic problems with the reliability of their lighting. It's especially embarrassing when you get faults with lighting that was completely renewed, cabling and feeder pillars and all, and lots of it fails after a year or two. Why are we having so many faults nowadays compared with decades past? Is there something fundamentally different about modern cabling and feeder pillars?
