Street lights and wiring for LED's

1)In HO scale, what is the normal distance between street lights.

2) What size wire do you guys use when wiring up your lights to a power supply?

3) When using LED lights if a resistor is required as an example, you needed a 460 size could you put (2) 230 size back to back?
I realize the values shown may not even be right but the concept is what I am asking.

Resistors in series: Ωtotal = Ωvalue + Ωvalue + Ωvalue
2000Ω = 1000Ω + 500Ω +500Ω
Resistors in Parallel: Ωtotal = 1/((1/Ωvalue)+(1/Ωvalue)+(1/Ωvalue))
200Ω = 1/((1/1000Ω)+(1/500Ω)+(1/500))
In Parallel, the total resistance, will be less then the lowest value resistor.
