The Main beam on the headlights don't work but the high beams do, thinking it maybe a relay?
The headlamp circuit is rather simple. From the 15 amp RH headlamp fuse, there is a red w/yellow trace that goes to the RH high beam. Out of the 15 amp LH headlamp fuse, the wire going to the LH Hi beam is solid red. Both of these wires should have power when the headlamp relay is energized. The wires from the Hi Beam bulbs going back to the switch should both be red w/black trace. The wire going from the headlamp relay to power the 2 15 amp fuses is white. The headlamp switch applies a ground to illuminate either the Lo Beams or the Hi Beams.

[Information] For a 2002 Toyota Camry, the Daytime
Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to
the center of the vehicle front) at a reduced power.
[The troubleshooting process:] Review the Owner's Manual and ensure the test
configuration matches the following criteria:
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness
when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."
2. Set the Test Conditions according to Step 1 above.
3. Check the headlight bulbs to ensure they are not
burned out. If one burns out, there is a fair chance that the other would have burned
out at the same time. Replace as necessary.
In this case, if the high beams operate, the DRLs should also operate.
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function
Switch on Turn Signals in "DRL" position, headlight switch off
(repeating what the manual says -- it should be obvious that in the
"DRL" position, the headlight switch should be off / do not have the
switch positioned to "High Beam"), and the Parking Brake
"off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box.
there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3).
Any one of them could be bad (stuck or burned out). Test (step 4).
7. Other less likely possible issues
could be that the Multi-function Switch is broken or a connection / wire is
broken. [Beyond the scope of this
process.]
My problem was that the test configuration did not have
the engine running and parking brake off - Step 1. Problem solved with much
thought, repetitive tests on the vehicle and going back to the basics -- what
does the Owner's Manual say and where are the applicable fuses and relays
located?

There are no buttons on the solution, ("yes or No") how can i say?
