The yellow type you get on most streets and roads. I know they are sodium or something so that they are low-power consumption, and that they have light sensors to switch themselves on and off... but still must cost a bit to run just one streetlamp.
Ideally I'd like to know how much it costs UK Gov to run all streetlamps in UK for one nights worth of operations.. but I doubt anyone could guess at how many streetlamps the UK has.

Depending on the wattage, it can cost between $50-80US, per year to operate one bulb.
"The council funds the majority of street lighting across Essex, a total of about 120,000 lights. The annual energy consumption of this is 44 million kilowatt hours of electricity, producing 19,000 tons of carbon emissions." = 1,802,875.79 GBP annual cost

The lamps are high-pressure sodium, and they come in various sizes from 35 to 1000 watts. Since such lamps are on for an average of twelve hours per day, the largest ones would draw 12 kWh per day, worth about US$1.50. But many street lamps use bulbs much smaller than 1000 watts -- 75 watts is common, and that would be 0.9 kWh per day, worth about US$0.10 (about 5 pence).
