Will interior light drain battery overnight
2018 300h: A friend left his rear seat light on and I wondered if it would have killed the battery overnight. If it’s an LED, how much could it draw?

All of the interior lights should turn off automatically 20 minutes after the engine is shut off.
For the 2017 ES, this is explained on page 381 of the manual. For the 2018 ES, the exact page probably isn't the same, but it should be close.

One time I left the trunk open in my garage for several hours. When I discovered it the trunk light was out. I thought the light bulb burned out, but as soon I closed the trunk and opened it again, the light came back on which makes me think the trunk light times out too.

Here is the list, from the manual, of interior lights for which this applies.
• Outer foot lights
• Personal/interior lights
• Door courtesy lights
• Ornament lights (if equipped)
• Footwell lights
While the manual doesn't include the trunk light in the list, I'm confident in guessing that the trunk light turns off automatically in the same way. Also, note that, while 20 minutes is the default auto shut off time, that time can be changed via the custom settings.
