tap'er light = "take it easy" or "have a good day"

[kid a]

from wiki:

It literally means, "take it easy," or "be careful and have a good day." It comes from the practice of setting explosives in the mines, they had to pack in certain types of explosive charges by carefully tapping them in with a hammer. Hit the charge too hard, or miss and strike a spark off of rock, and ka-BOOM! (grin) Lots of cowboys in the local area who supplied beef cattle to the miners picked up the saying, so it spread amongst cattlemen too.
