The filament is nothing to do with the light turning on, that is controlled by the switch.
No, the type of bulb and filament will determine life, as well as how many times it is turned off and on. Repetitive on and off cycles will reduce the life of the filament.
it come from the energy source in the middle of the light bulb he clearly asked what type of energy is it?!
For the filament tocatch fire you need to have oxygen present so depending on the type of light bulb it may be a vacuum inside or have some sort of inert gas inside that is not oxygen.
The original Edison light bulb used a carbon based filament, later a metallic filament (tungsten) was used to increase the life of the bulb. Today the government has mandated that a fluorescent type bulb be used
I think this is your vehicle (see related link) so you need 380 type bulb. A basic filament bulb costs from £1.28, An upgrade LED type bulb costs from £8.20
