Turn on keyboard backlight from multi-user.target

Is there a way to turn on the keyboard backlight from the multi-user.target environment? As X11 is not loaded, the command xset led on does not work and gives xset: unable to open display "". Currently, I am wanting the keyboard backlight to turn on each time the system starts (only if the keyboard is present). I would also like the keyboard backlight to turn on regardless the system loading in a graphical or non-graphical environment. Preferably, I would like this done through Cron.
