Lights came on when car off. battery dies - 1999 Toyota 4Runner

Replace battery

I suggest to check some paraticis drain and ground connections. Additionally, check and test alternator charging.

the car is imobalised, try disconectint the earth from battery for 5 mins and reconect, car should start

maybe your fuse is bad?

Your battery is either dying or your alternator is bad. It is not charging the battery therefore, the battery light comes on and then the car dies.

You can have both checked at any auto parts store for free.

Is the alternator charging? recharge the battery with a battery charger, and then have the battery and alternator checked on the car.

Thatttttt's alternatorrrrr.

Your alternator charges your battery. No alternator, no battery charge.

YOU PROBALLY HAVE A NEGATIVE POWER DRAW TO CHECK THIS USE A TESTER LIGHT AND CLIP THE WIRE TO THE POSITIVE SIDE OF BATTERY AND TOUCH THE NEGATIVE BATTERY TERMINAL IF IT LIGHTS UP U HAVE A NEGATIVE POWER DRAW

Try cleaning the battery cables where they contact the battery. If that doesn't do the trick, most auto parts stores wil ltest your battery for free. Do both first before lookng into the charging system. Alternatively, Place an external battery charger on the battery and charge it up. If that fixes it  then test the charging system.
