Driving around last night with the low beam headlights on. Flipped on the high beams to look down the road and the car goes whacko.
Throttle goes dead, speedometer drops to 0mph, and every warning light illuminates. As soon as I flip back to low beams, car is back to normal.

Tried it 3x and each time the above happened. Really at a loss for this one. Anyone have any idea what's going on?

cps sensors is first guess

Is the CPS connected to the lighting system somehow?

Seems like you have dirty battery terminals.

they pass enough current to run the car and power low beams. But not enough to power the car and high beams.

I imagine that the starter motor runs kinda slow as well.

Seems to start fine. Doesn't the alternator take over once the engine is going?
I'll double check the terminals and tell you what I find.

Do a load test and see if your alternator can support the load! You maybe able to use your OBD2 tester to test your electrical systems if you have one with that feature...
