Re: D600 AF assist light Issue

See page 223 of the manual: There are several limiting factors.

a7: Built-in AF-assist Illuminator G button ➜ ACustom Settings menu
Option Description
The AF-assist illuminator lights when lighting is poor (viewfinder photography
only). AF-assist illumination is only available when both of the following
conditions are met:
1. AF-S is selected for autofocus mode (097) or single-servo autofocus is selected
when the camera is in AF-A mode.
2. Auto-area AF is chosen for AF-area mode (099), or an option other than autoarea
AF is chosen and the center focus point is selected.
The AF-assist illuminator does not light to assist the focus operation. The camera
may not be able to focus using autofocus when lighting is poor.
A The AF-Assist Illuminator
The AF-assist illuminator has a range of about 0.5–3.0m (1 ft 8 in.–9 ft 10 in.); when using the
illuminator, use a lens with a focal length of 24–200 mm and remove the lens hood.
