Having spent 20 years in human factors this is news to me.  The main concern
for the location of warning lights is putting them in the most conspicuous
location. Since they typically have labels that need to be read the left
visual field  presentation makes little sense.

is it my understanding that warning and emergency lights are usually
placed on the left in automotive and aviational settings,so that the info
would reach the right hemisphere and hence cause quicker reaction time?
