I do a fair amount of work on streetlighting faults which are certainly a challenge sometimes. There is not much logic in the way the circuits are run and a lot of damage is usually done by roadworks which mostly damage the streetlight circuits. Also overloading is an issue and not always enough contactors are fitted in the streetlight strings running via the pilot system from the substations to serve the various roads in a certain area. Biggest culprits are the new subdivisions. Can't comment on the traffic lights. but a POCO job is not too bad at all.

Traffic signal contractor? I know people that do it and made a hecuva lot of $ selling the old lights; yet I knew a guy who got killed doing it. (Semi truck knocked of bucket from arm.) If you want to do it, you'll be pulling wires under roads, through poles and mast arms, wiring the controller cabinets (nightmares), hanging and securing the lights by yourself, then wiring them. Oh, and you get to work in a bucket truck a lot. Still interested? Look in your phone book to see if there's a contractor (usually an EC) that does them. If there isn't, the township/state handle them.
