The inrush current happens as the light.. lights up, so you are talking a few dozen milliseconds at most. NBD.
Addendum to Newtons first law:
zero vehicles on jackstands, square gets a fresh 090 and 1911, cabby gets a blower.
EZ3.6 Vanagon after that.(mounted, needs everything finished) then Creamsicle.

There is potential for inrush in lighting that uses ballasts such as hps or some types of fluor lighting incandescent lightings inrush is not that significant
You usually only worry about inrush with cooling fans and fuel pumps and things of that nature and inrush only lasts micro seconds most fuses get around it and not a big concern for any kind of switching
Eg. my wifes filter queen vacuum draw 7 amps running i have a bunch of highly accurate metering equipment on my work bench i have seen this same vacuum spike between 80 and 100 amps on startup but this spike is of such a short duration it is really nothing to worry about
