Ace cafe - 20th July

[Niall]

Yeh on the m25 the ones at the top only come on when the signs are on... i believe....

and the ones on the side of the gantries are on all the time....

something even newer appears to be a flash cone... so its not a directed flash like normal its  abeacon that flashes in one direction. I was distracted at 9am in the morning. No idea what they are playing at! I was doing 70mph and it must have gone off 4 or 5 times in the opposite direction!

The ones on the gantrys are on all the time but not all of them work!
The ones at the side of the gantrys all work and can be difficult to see, theres no road markings. None of them work below 70mph regardless of the speed displayed on the signs
The ones on top of the gantry will sometimes flash once. This isn't flashing someone for speeding, its just a self test.
