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: High Beam Indicator blinking
My lights have had this problem for months. From time to time I try to fix it, but I have learned the following:
1. [EASY SOLUTION] After turning off the car and turning off the headlights, when I pull the headlight switch back (toward me) and then let go, the running lights turn off. [/EASY]
Extra information that I haven't figured out how to use yet:
2. Apparently the DRL bulbs operate through the high-beam bulbs; this is why you get the high-beam light when the DRLs are broken (or whatever) and why you can turn them off with the high-beam switch.
3. My wife took the car out for a fluid change once and said the mechanic pointed at a light on the car and said, "that bulb's out," and that if she fixed it the DRL's would work normally, but she forgot which light it was. He even told her what bulb it needed. I took it to the same place and no one knew what I was talking about.
I don't think about trying to fix this very often since I realized I could turn the lights off with the high-beam switch. I used to worry that that blinker was somehow draining the battery, but it never has (whereas I once drained a brand new battery just by leaving the interior light on all night). I hope I've helped!

This may be the start of a worse problem that the Impala eventually developes. The Body Control Module has a design flaw along with the Passlock anti-theft system. You may get away with just replacing the BCM for now. It needs to be reprogrammed at the dealer and the car will not start if you replace the BCM without reprogramming it. I would also recommend against replacing it with a remanufactured one. Repair cost is going to be around $500 at the dealer.
If the Passlock system is also at fault, add another $500 for a new ignition switch and cylinder. If you haven't experienced random starting problems yet, they are coming soon. When you turn the key, nothing happens. I thought my 2002 Impala may have been immune to these problems that I've heard about constantly, however, at 90,000 miles, it became "possessed". The symptoms started slowly and got worse. Beside the interior lights flashing like strobs in the middle of the night (while the car was not running), the headlights would occasionally click off and on a few times while I was driving at night.
The relay switch you hear clicking is the Battery Rundown Protection relay. I'm suprised your battery hasn't drained to the point where the car will not start in the morning.
