i was thinking of replacing my blinking LED on my alarm to a different 1 neon strip 12volts.

would this kill my battery over night?

Ok , to answer this question you need a very simple math after you check your battery condition; lets assume your battery is in good condition:

1- look at the Ah( amp hour) of your battery . lets say it is 50 Ah
that means if you use your battery to power a device that uses 1 amp (which you can call it 12 Watt device) it will take 50 hours to drain your battery and if you have a device with 25 Amp it takes just 2 hours to kill your battery and if you have a device with 100 amp operation it takes just half an hour to drain all your battery power.

2- look at the the "neon strip" you want to instal on your car which it tells you in which Amper it functions. Then use number 1 explanation....
Just remember main useage of battery in the car is powering the starter which is extermely high Amp device but good news; we use the battery for couple seconds to start our car
