What makes a Kenworth Truck turn on high beams?
On Kenworth trucks from 2005 – 2010 have a module that controls the headlamps and turn signals. If the module detects a burned out low beam it will turn on the high beam at reduced intensity as a safety precaution. Your symptoms sound to me like you got both low beam bulbs burned out and the truck is auto-illuminating the high beams.

Why are the blinkers on my truck not working?
It is not a fuse issue, checked both flasher, and blinker fuses. SOMETIMES they do work, majority of time they do not. Sometimes they flash ONCE then stop flashing. No lights on dash when they are not working. No sound (our blinkers beeep when engaged). Started last night, no major truck issues happened besides this.
What makes a low beam light up in a high beam light?
The low beam bulb has two filaments in it, one for low beam and one connected to the high bean circuit. When you see all four lamps illuminated in high beam, that is due to the secondary filament in the low beam bulb. Replace your low beams and I’ll bet everything will work as expected.
