Original battery was/is lexus
Group 35 Battery
RC: 80 Min.
Height Over Terminals: 8.62" Terminals: SAE Auto Post
Chemistry: Maintenance Free - Flooded Lead Acid
Batteries don't last long 3 years at most, an old battery will not hold charge over time as the cell become clogged, this is the info of the 1991 battery that was originally fitted.

More then likely your vehicle has a parasitic drain on the battery . A control module may not be powering down or something is on in the vehicle. Testing the electrical system like in this video is the way to find out .

SOURCE: all dash warning lights came
You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.

Try rotating the ignition switch slightly after you turn it to on and see if the lights come on...had the same problem and changed the switch fixed the problem...

your battery is dead!! Even if jumped, if the battery is dead celled it will not have sufficient power to crank. Dead celled batteries will hold a charge momentarily then slowly die again. I recommend temporarily swapping a battery from another vehicle to try and start your ES300. This is to make sure it isnt the starter or alternator thats the problem. To test the alternator, use a voltmeter at the battery terminals (w/car started and running) to check voltage should be (13.5-14.5 volts). If you do not have a voltmeter,(old school way) simply start the car, while engine running pull the positive terminal off the battery(make sure NOT to ground the positive terminal). If the vehicle dies, possible alternator or alt circuit failure. Bring it to autozone or advance auto to test for free. Hopefully this helps...please rate...thanks
