The battery in my car can supply 2500A to a short circuit, does that mean the 21W indicator lamp needs a 2500A power supply?

The alarm is designed to run for, presumably, quite a long time on batteries, so the current draw won't be much.
500mA SHOULD be enough, but if you can, get one that will supply more (say up to 2 amps) - then you know it will work.
