This shows a setup with a screw-in adapter that makes a LED conversion easy, by not having to remove the reflector and bulb socket. Also good for returning to incandescent in an emergency when there are no LEDs on hand.
@basilicon89, Yes is glass, starting to lose it's "mirroring"
@streetlight98, I generally carry enough spare LEDs on my truck, but I do have each a R-Y-G lens and an arrow mask just in case.
@LilCinnamon, The incandescent lens is removed prior to installing a LED.
@ Joe- Yes. They did in the mid to late 1990s. In the 1990s several manufacturers (Electro Tech and McCain notably) produced a Red LED fixture that utilized the existing lens. The setup proved to significantly reduce brilliance. I have a picture of a McCain version somewhere. I'll have to look.
LED modules bought new are very expensive. I brand new countdown is $200. I believe Green modules are $200, Reds are about $150. Don't know yellows off hand.
If you know anything about this industry its that nothing bought from the factory is cheap.
For fun, here are some prices for stuff bought from distributors:
Start with something little... pedestrian crossing buttons---cheap?
Polara Bulldog (The pressure sensitive buttons that beep): $150 EACH
Polara Navigator (the ones that say "Wait" and "Walk sign is on"): $400 EACH w./ voice unit
Continuing on...
Video Detection Cameras range from $800 to $1,200 EACH
Cabinets with all the equipment (video processors, conflict monitors, terminal facilities, etc) are roughly $25,000
A controller such as my EPAC M50 bought new is $5,000
Signal heads themselves range from $300-400 for a single 3-light signal.
A programmable signal such as a 3M, or a McCain, or Intelight is about $1,200 EACH
Add the poles, detectors, all the heads, LEDs, controller and all the wire. Plus interconnection equipment if needed.
Most municipalities invest $250,000 to run an intersection. It is nice to have the "collector market"
One traffic signal setup on the road just with one pole for one direction of the road, the whole setup for that direction would be like.. 7 or 8 thousand dollars. With four.. Quadruple that. O.O
Yeah those prices are really ridiculous, I mean sure the're a lot of components and the material has to meet certain standards but still ...
Here for an signal replacement the government allocates $100, 000 - $150, 000. @ Ian I got about $32, 000 for the set up you mentioned, I think you forgot the control cabinet, pole, mast arm and street light not to mention labour
@ LilCinnamon. Thats about right for the actual pole, cable and lights. But factor in all the cabinet components. Controllers are $5000, Conflict Monitors are $2000, The Load Switches are about $200 each (X12 in a large intersection) Flash Transfer Relays are $50 each (X6 in a large intersection) Then you have things specific for the intersections like Ped Isolators for the buttons, Video Detection Processors for the cameras, Opticom Units for the Emergency Vehicle Detectors, The backpanel itself. I was quoted on some power supplies from Naztec recently...$500 per supply. BIUs are about $500 and cabinets that have them usually use two. Add interconnection equipment, hardware for all the signals, lines to a closed loop master, either via fiber optics or radio wireless. Some new cabinets are outfitted with a radar traffic counting system made by "Wavetronix" those are about 3 grand to install. Then yes labor and all that. You're easily hitting $150,000-$200,000 for a fairly large intersection.
Remember the city does the build gradually, and spreads the cost out over time as the budget allows. Here there is a big issue with maintenance, as there are a lot of intersections that have regular cable theft.
I have been replacing several TS LEDs lately, they seem to fail in "spurts". We can go for months, not replacing a single LED, then a whole lot need replacing. The summer heat usually causes more to fail.
I've seen ones that screw in for ped signals but not for vehicle signals.

@Niall, don't know how much the LEDs sell for new but I have bought used ones for $15 before.
