91 Camry, Lights on indicators not working
 

Title pretty much says it all. I have a 91 Camry DX sedan, and I've gotten most of it restored, but the lights on indicators don't work, so I have to be careful to turn off the lights or I come back to a dead battery. Though I am used to it for the most part, this is annoying, as you can guess.

What would I look for in terms of repairing that circuit?

Thanks in advance for any help that you can offer.

The instrument console, climate system lights, etc? If so, do any lights work?

How about taillights and glove box light?

Hi, yes, all of the lamps work. I see "Lights" when I turn the car on, so I don't have to replace the bulb. The problem is, it's not activating when I have the lights on.

The car isn't in bad shape. The engine was replaced two years back, the battery last February, and according to the local Toyota dealer who did a full diagnostic for me, I need to replace the muffler and an EGR pipe, and there's a slight power steering leak, but otherwise everything seems functional. The lights all work, interior and exterior, cruise control, power locks, power windows, A/C, all good. I just replaced the resistance coil so the A/C works on all levels, not just high. Tail lights are good, trunk lights are good, and I even replaced the license plate frame lights on the back, so they are good. Not sure about the glove box, hadn't thought to look.

I left the lights on for about 4 hours last night, but was able to start the car up this morning just fine, so I would say the electrical system is in good shape.

I am thinking it might be a fuse, but I don't know where the fuse box is.

The lights (are) on indicator light?

You sure the car has one? None is listed.

I can photograph it. Yes, it's on the right side at the bottom, three under the oil light indicator. It might just tell me if a light is out, but it would seem to be what I think it is. Are there cars without the funactionality to warn you if the lights are on when you exit the vehicle?

Great!

There is an indicator if a tail or brake light is out and a high beam indicator.

There are cars without a warming light. The next generation Camry had no warming system.

I checked elsewhere, and there should be a chime. It was said that it's part of the integration relay, though everything else covered by that circuit works fine (radio, dome lights, power windows, etc.). But at $150, I will probably just have to commit to muscle memory the act of switching off the lights every time I turn off the car.

Buy a add on buzzer from an auto parts store.
