Even Optima did an example of a 17mA drain on one of their ~70AH batteries. (IMO purely academic - and Optima would have failed way before that... LOL!)
50mA is more than 2 LEDs, and even one LED can be considered a problem (viz 17mA example).
Vehicles with ~50mA alarm drains have problems after a few days.
Not to mention their shorter battery life.
