Around 100. You just have to know how to squeez them in there. You might have to put in a few upsidedown.
about 12 seconds See related link for specs on the Nissan Micra
it varies from model to model, but from my time working for nissan, they were generally 32psi front 30psi rear
Possible Dizzy cap!
The only time you should have to worry about it is if you have problems. Nissan repair says approx. every 100,000 miles
This can only be replaced by a Nissan dealership or should be for safety reasons and that's all that i would trust it to because it not installed properly it could go off at any random time.
The same time as a regular sized man
Your best option is to get hold of the car manual or failing that watch mechanic changing bulb so that you can do it yourself next time, this techniques has worked for me on Nissan micra.
No black dwarfs are thought to exist. The estimated time it takes for a white dwarf to cool to a black dwarf is greater than the current age of the universe.
Dying stars eventually shrink into white dwarfs (which as they age eventually become red dwarfs and then brown dwarfs - but this takes an extremely long time).
with time
They are called white dwarfs because when they form, although not replenishing their energy supply any more, they are still hot enough to shine. Overt time (a long time) however, they will cool down and become 'black dwarfs' which no longer emit light in visible wavelengths.
According to astronomers and authors Jonathan Weiner and Carl Sagan, white dwarfs - which have been an accepted entities by all astronomers for decades - require an amount of time to "cool down" that well exceeds the current age of the universe - hence there hasn't been enough time for any of them to cool down yet and become "black dwarfs".
