Electricity

The streetlights do they automatically connect to your grid or is there an extra step you need to take?

You just need to check in the config notecard. Set as below to have them connect to the region grid.
# Set to 1 to auto-connect to region power grid
ON_GRID=1
# Can be  Electric  or  Gas
ENERGY_TYPE=Electric

Hi the conf card didnt have that, I tried adding it and still not working.  This is what the conf card has now after I added ;\
Set to 0 for no float text
SHOW_TXT=1
#
# Can be  Electric  or  Gas
ENERGY_TYPE=Electric
#
# What fuel object to accept if not connected to power grid
FUEL_NAME=SF kWh
#
# Set to 1 to auto-connect to region power grid
ON_GRID=1
#
#Set to 1 for automatic mode where light comes on at night and off during day, 0 for manual mode
AUTO=0
#
# Default language
LANG=en-GB
#
# Optional light settings
#    Radius: Specifies how far the light travels, in meters. The maximum is 20 m
#    Falloff:  Sets how quickly the light's Intensity fades as it travels to its outer Radius. Lower values are more gradual. Range is 0.01 to 2.0
#
RADIUS=20
#
FALLOFF=0.01
#
# Brightness of light from 1 (minimum) to 10 (maximum)
BRIGHTNESS= 10
#
# Colour of the light
COLOR= <1.000, 1.000, 0.800>

If it was set like that then it should be able to connect to your grid. Do make sure that the group the light is set to matches the group the electricity controller is.

Also I have found sometimes you need to click on the light and select Disconnect, then click again and reconnect it.
