Should I switch off the router overnight? Will it use a lot of electricity if I leave it on overnight? Would it damage it if I switched it off for periods of time every day?

A typical red neon bulb uses 1mA of current. That means its power consumption (including that of the series resistor also present) across a 240V supply is 0.0001 x 240, or 0.024W.
Since electricity in the Uk costs about 10p per unit, or kWh, you will get about 40,000 hours of use of the neon for 1 unit costing 10p.
There are about 8700hrs in a whole year, so 4 years for 10p.
I wouldn't get excited over it.
