Vehicle warning lights are like traffic lights - green = go, Yellow = warning, Red = Stop the vehicle!!. Most vehicle manufacturers recommend that if the Check Engine Light Comes on the vehicle is safe to drive to your nearest repairer.. G'day fro Aus!!
It is safe to drive you car for at least one mile after the check engine light comes on.
The USB lights on your laptop comes on when your USB flash drive is not working.
If the green lights go out for the 4 wheel drive and the yellow light comes on in an Infinity QX4, there could be a problem with the transfer case. There could also be a problem with the 4 wheel drive not engaging when it should.
check your cars battery lead terminals i had a similar problem in an olds eighty eight, i would hit the brake to be able to shift it into drive and when it wen tinto drive the lights would dim noticabley if it was night and the engine would die. the trouble turned out to be that the battery terminal leads were heavily corroded and at idle when shifting from park into drive the brake lights being on the abs pump bein on and such caused a large enough voltage drop that the ignition would not have enough to fire the engine and the engine would die.
If an engine transmission light comes on in the dashboard there can be a potential problem with the drive-train. The engine's computer should receive a diagnostic to determine if there is anything wrong with the transmission.
The light is NOT a low oil light. It is a low OIL PRESSURE light. You can drive it until the engine seizes. Of course internal engine damage will start to occur as soon as the light comes on and you have no oil pressure if you continue to drive the vehicle.
You will have to drive it until it comes on.
FR means Front-Engine, Rear-Wheel Drive
Absolutely. Being deaf does not effect your ability to drive. Emergency vehicles have flashing lights besides sound for a reason.

Im pretty sure you are having a loose ground wire somewhere in the engine bay
