View Full Version : R/W Light fitting, positive ID required

One for Carnaby here I think!
This was found about a third in from the R/W edge. I only had a brief stay at the site, but this was the only one I found, though I think there may have been at least one more covered up on the R/W verge. It is in superb condition, with absolutely no corrosion, not apparent in pics was its 'chinese hat' shape.
I'm guessing this is a Drem single direction light fitting, but really want to positively confirm if it is or not?




Thanks in advance

It's a Drem Mk.II fitting, typs 'C5'. Most commonly used as a 'Crossbar / Cautionary Zone' fitting as a line of seven at 25-foot spacing across the runway, 800 yards before its end, to warn the pilot that he had 'just enough' runway left. (Two lights would be in the grass 'prepared area' outside the hard surface).
They would be blue screened and often the two which coincided with the actual edge of the runway would be standard bi-directional 'C6' flarepath fittings, i.e. combined with the runway lights.

They were also found on FAA airfields as 'Open-Up and Go-Round-Again' lights. Same purpose, but instead of being stretched across the entire runway, they consisted of two bars of closely spaced fittings at each edge of the runway.

A good find in excellent condition. Dare I ask where it is (was!) ?

Nice find and in excellent condition for its age.
Very surprised it is still fitted after all these years.

this looks like what was fitted at North Witham, the holes are still present, fittings long since gone (pic of the ole' on east mids thread),

On the subject of positive identification of runway lights! Does anyone know what is the correct term for this light?

I assume they are stop/go lights to enter the next holding point? I have flown a light aircraft once so I am an expert :lol: :lol:

By the way I was told the EXPERT is made up of :-

EX = Has been
SPERT = Drip under pressure

Yes I know there is no "S" in Expert but the sound is there phonetically

PNK is correct I believe. Traffic lights were first introduced at the end of WWII as part of the AFL / Drem Mk.III upgrade, when runway / taxitrack layouts were becoming more complex.

The original system used a pair of red and green lamps mounted on a wooden (weakened) support. (Source: AP3236, Works)

Thanks for the confirmation guys

Apparently St Mawgan was the first place to introduce traffic lights on a new build layout, due to the size and distances of the taxiways, and complexity of the various dispersal areas.
They still play a major part in ground movements, here at SA there are 8 sets to control vehicle activity on around the runway.

It's a vehicle traffic light in this particular case I believe.

Yes.....I've spent many minutes (nay, hours) of my busy refueller days waiting at the lights at St Mawgan to turn to green, that is to say when those lazy a55ed controllers could tear themselves away from a riveting game of clag :roll: :lol:

At least the ones at Portreath were always off when I was working there :lol:
