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.

SOURCE: Low beam headlights not working
My brake light on my 1990 geo, Right side did the same thing. It was the ground wire on the light itself. It had gotten hot and was not getting good contact, so I put a small bolt with a nut on it thru the plastic light panel to help it make contact to the ground.

a possibility is the multifunction switch or the tipm being bad. check the wt/lg wire in the left headlamp assembly and the wt/tan wire in the right assembly for power

SOURCE: change head light
You should be able to reach under the hood into the headlight assembly and grab the bulbs and twist them off if not then you have to take off your entire headlight assembly then take the bulbs out.
