Are you aware that your car (2015 LS460) allows you to customize the sensitivity of the Automatic Lights sensor? If you increase the sensitivity you might get the lights to come on closer to the onset of rain.

Sounds Like you may have a defective doorjamb switch on your driver's door.

Yeah, they don't get sensitive enough, and I don't really want them coming on so early when it's not raining.

They really should come on with the wipers.

Roger that. I have DRL's, so that works for me.

Driving with only DRLs here in the rain is actually illegal, it's that way in most states now. DRLs don't activate your running lights in the rear either. In inclement weather for compliance with the law and safety your headlights need to be on.

Most cars with auto lights have lights that come in with the wipers. Lexus is behind there. Hell, my Dads 95 Cadillac had lights that came on with the wipers.

I just actually tested it and on my model-year car, and if I have the lights set to ON and turn the car off they stay on. As soon as I open the door, the lights go out. No need to press any button for me.

Pre spindle front bumper redesign

If selector is set to "ON" or "AUTO" when you get out of the car and lock x2 it will shut off lights.

If selector is set to "AUTO" when you get out and lock x2 it will shut off the lights.

If selector is set to "ON" It will BEEEEEP at you to turn off the lights when you open your door, and you can press the lock button until your FOB runs out of battery, but the lights won't shut off like they used to.

I have noticed that even with loaner cars, that after the model received the spindle bumper redesign, one of the many changes or "upgrades" included the new lighting logic. I am not saying this is because of the spindle bumper obviously, just noticed thats when these other changes happened.

Hope that clears some things up.

I think you're right. Always wondered why the RC350 loaner I get keeps on beeping at me when I leave the lights on 'on'.

When I first got my LS, I thought it was broken when the lights didn't go on when it started raining. I've increased the sensitivity and they still don't reliably turn on with the rain. What genius forgot to add that logic to the car? Kind of defeats the whole purpose of 'auto'.
