When this happens, it means one or two of the halogen headlight bulb(s) has been burnt-out.
Do this quick and easy self-test:
Turn on the headlight switch to LOW and see if you see one (or none) turns on...you'll know one or two lightbulb(s) need to be replaced....this is why the green headlight logo flashed to tell you that a bulb has just burnt-out.
You'll need to remove the 4 black plastic clips that holds the top grille bracket frame onto the top metal frame that's facing the top radiator area.
If you know which headlight's bulb need replacing, just remove the 3 bolts...two are on top and one is by the side (close to radiator area)
Then you pull the grille toward you gently to allow your hand to access behind the grille and headlight area to reach the white socket that's connected to the headlight bulb.
This requires some patient as it's a tight area for your fingers to wiggle the socket off.
When the new lightbulb is installed, the green headlight logo will appear in the instrument panel when you start the engine.

Check your o2 sensor voltage, those trucks are real bad for o2 sensors, and yes if one sensor is reading 0mv, the others will start to drop out, and the vehicle will run very, rough. You also may check fuel system pressure, should be almost 60p.s.i. If its alot lower, Id be looking into a fuel pump. If that vehicle is drive-by-wire (no throttle cable), the throttle bodies get very dirty and cause that concern also. Id start by having the vehicle scantested.

The blinking light is telling you that you have a headlight out, if you look the service light should be coming on when the light stops blinking.
Replace the head light and all should be fine.
