Travel through any roadworks at night and you'll see only a few SPECS cameras with powerful floodlights illuminating the road in front of the camera. If it needs this light to work, ...
It doesn't. SPECS uses infra red illuminators.
Which obviously don't work. Otherwise, why the floodlights?
The floodlights are normally set up at the point where vehicles must change lanes, e.g. shifting 1 + 2 to 2 + 3, or to illuminate the entries and exits used by works traffic to leave the running lanes into the roadworks. AFAIK they are never associated with camera locations. They usually shine across the carriageway perpendicular to the direction of travel to avoid blinding drivers in either direction.

Yes, those are present too.

But some are right in front of SPECS cameras and illuminate a line across the whole carriageway.

Avoid blinding drivers? That's a joke. The ones to which I refer give your eyes a huge whack. I always wonder if this might trigger epileptic seizures.

+1 yes

They have these lights on the M1 @ J16 ~ J19 and as you pass under them they blind you for a split second (it hits your eyes like a camera flash going off in your face!).

I also noticed that the lights were set up to shine across all three lanes just where the average speed cameras are located and I don't recall there being any works entrances at the same places.

I had assumed that they were to illuminate the drivers so anyone caught speeding couldn't claim it wasn't them.

The OP saw the sign but insists due to low sun could not read the number.

If that is the case he should have been thinking I was in an NSL, the limit has now changed and the only way it could have changed is lower, I should be checking for clues to the new limit.

Roadworks
Reduced width lanes
Speed of other traffic
Gantry repeaters etc etc


On another note, does anybody have a car which has the camera fitted for reading signs? How does it fare in low/blinding light? Would it have picked up the sign in this case?
but you are wrong
the road works hadnt started
there was no reduced width of lanes yet
there wasnt alot of traffic
there wasnt a gantry repeater as the first camera was behind a bridge

suggest you read the posts before making wild suggestions

I have just driven South through these works in the last 15 minutes and can confirm that there is indeed limited signage.

There is an initial sign which warns that disruption will take place until 2016, then there is one pair of 50 signs, then within perhaps 60-70 metres, a bridge with the Specs cameras hiding just behind it. That's the extent of the advance warnings; I was convinced that there was loads of signs before the start of the works, but there is definitely not.
thankyou

its dangerous isnt it?

Saw these lights today, never seen them like that before. Agree that they appear to be for illumination to aid the cameras. Also noted that the cameras are not shining visible red light like old SPECS.

Also, on the M3 saw rear facing SPECS. Watch out bikers and skinflints who only put one false plate on the front of your car.

There's plenty of warning that the roadworks are coming up. And roadworks on a motorway tend to mean a 50 limit, no matter what your camera detector says.

Should've been more observant, sorry.
So, how do you engage your power of observation in the OP's circumstances, when the low sun makes signs impossible to see?
my point exactly.. the signs are unreadable at low light, and with lack of signs or cones, with no clouds hard to know unless you use the road or seen the roadworks before
