= Kareful running In LED Light?
good guess.
Keskiviikkoillan lamppulenkki.
(Wednesday Evening Lamp Jog).
English version WELJ might sound cooler than KILL, but I don't need cool names so I use Finnish version.
OK, so my guess wasn´t too bad after all. I only missed on the Wednesday evening part - both the kareful running (=jog) and the lamp was correct ;)
