To my knowledge a 2003 Toyota Camry uses a dual filament halogen bulb, either by Osram, Philips or Sylavania. If on the dashboard, the blue indicator lits when the switch is moved to bright or the passlight is engaged but no headlight, then it could jut be busted bulb (or part of it since you still have driving/low beam). In some cases, it could be the relay that supplies power direct to the bulb. At other times, it could be fuse(s) assigned to high beam. At certain instances, it could be also a loose, corroded or burned connector.
Corrective measure for your concern would be to check the 2 bulbs. This is performed by removing the rear covering (rubber or plastic cap) of the headlight assembly from the rear. The bulbs are held in place by a spring clip that needs to be unlatched from the base/holder. Carefully remove the bulb taking care not to touch the glass envelope. The filaments would be readily visible and cut/breaks would be apparent. If determined that one of the filaments (high beam) is open, replace the bulb(s).
If the bulbs prove to be OK, you need to work yourself backwards tracing the wiring harness. After the bulb, check the 3 prong connector for any corrosion or scorching/burnt marks; clean as maybe required. Next to check would be the relay that provides the +12VDC and then the fuse.
I doubt if the dashboard or steering wheel components involve with headlights may be at fault.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

Hi. i recommend a thorough inspection of the wiring harness and harness connectors that led to the actual headlights. use a volt meter to test the current flow to the connectors. pull the connectors from the back side of the headlights and test all cooper contacts inside the connectors. If the wire contacts all show voltage, this will confirm a switch malfunction. it should be replaced in this case.
Now, if one or more contacts on the wires harness fail to produce any voltage, this will confirm a faulty wiring harness. replace the wiring harness in this case.
Make sure the headlight switch is in the on position when testing the wires.

AIMING THE HEADLIGHTS
The headlights must be properly aimed to provide the best, safest road illumination. The lights should be checked for proper aim and adjusted as necessary. Certain state and local authorities have requirements for headlight aiming; these should be checked before adjustment is made.
CAUTION About once a year, when the headlights are replaced or any time front end work is performed on your vehicle, the headlight should be accurately aimed by a reputable repair shop using the proper equipment. Headlights not properly aimed can make it virtually impossible to see and may blind other drivers on the road, possibly causing an accident. Note that the following procedure is a temporary fix, until you can take your vehicle to a repair shop for a proper adjustment.
Headlight adjustment may be temporarily made using a wall, as described below, or on the rear of another vehicle. When adjusted, the lights should not glare in oncoming car or truck windshields, nor should they illuminate the passenger compartment of vehicles driving in front of you. These adjustments are rough and should always be fine-tuned by a repair shop which is equipped with headlight aiming tools. Improper adjustments may be both dangerous and illegal.
For most of the vehicles covered by this guide, horizontal and vertical aiming of each sealed beam unit is provided by two adjusting screws which move the retaining ring and adjusting plate against the tension of a coil spring. There is no adjustment for focus; this is done during headlight manufacturing.
Because the composite headlight assembly is bolted into position, no adjustment should be necessary or possible. Some applications, however, may be bolted to an adjuster plate or may be retained by adjusting screws. If so, follow this procedure when adjusting the lights, BUT always have the adjustment checked by a reputable shop.
Before removing the headlight bulb or disturbing the headlamp in any way, note the current settings in order to ease headlight adjustment upon reassembly. If the high or low beam setting of the old lamp still works, this can be done using the wall of a garage or a building:

Testimonial: "It's great to know that there's not a whole lot more to check! I wouldn't have guessed I was so close. Thanks!"
It sounds like you are confused about how your headlamp system is supposed to work. The DRL does not run on the High beam circuit, it runs on the low beam circuit. The fog lamps are supposed operate with the park lamps and also with the low beams, not the high beams. From your description, I would say that your system is operating as designed and you are having trouble telling High from Low. (Don't feel bad, that is why high beam indicators were invented in the first place.)

Turn the engine off, open the hood, and disconnect the negative battery cable (--) with your pliers.
Locate the power distribution box against the firewall on the driver's side of the engine compartment. Flip up the latch and remove the plastic cover.
Determine which headlight fuse you want to replace. The 2001 Ford Focus uses four headlight fuses--one for each headlight. Fuse number 16 is for the passenger side low beam; fuse number 17 is for the driver's side low beam. Fuse number 26 is for the passenger side high beam; fuse number 27 is for the driver's side high beam.
Grasp the fuse with your fingers and pull it straight out of its mount. Insert the new fuse in its place. Replace the plastic cover and reconnect the negative battery cable.
