Classic British traffic light incandescent lamps

[Alex]

Hello everybody,

Cananybody advise me what incandescent lamps were used in british traffic lights? In Philips 1989 UK catalogue i found a 65W long life incandescent lamp with ES cap and the M/28 and M/32 halogen lamp (G6.35) amps.

I had a glance at GEC and Thorn catalogues. Thorns 1988 catalogue list the same lamps as Philips. GEC too.

Are these all the Lamp types used in the UK? I am aware of low voltage Ba20d based lamps with single or double filaments that look similar to german traffic signal lamps. However my examples of these do not have an etch, so exactly identifying makes it difficult.

Also does anyone have pictures of the three lamp type mentioned above they could share?

Incandescents that are 65w are old, old traffic light lamps. I've got a couple of traffic lights dating from the 1930's and 1960's respectively which take 65w GLS lamps, but from approximately mid 80's on (I think) traffic lights here used 12v 50w halogen capsules mounted in the centre of a large reflector behind the lens, and then moved to flat LED cluster cards in the last decade or so.
