But, and I noticed this last week and I have a Gra Lab as well, the safelight WILL NOT come on unless the timer was just on and has just run out to 0, as in after exposure of the paper. If you turn on the enlarger to compose another print you lose the safelight for placing paper on the easel until after the timer has run out.

So I bypassed this deficiency (IMHO) by, as aforementionedly mentioned aforely (wow, where did that come from), plugging the safelight into another outlet, not into the side of the timer.
