I doubt his ‘night light’ in the house requires power hungry incandescent bulbs. Warm white would give a nice original looking glow.
Some people are OCD, purists, or just don't want to change something from how it originally was.
In my case, I'm extremely OCD about originality. Aesthetics isn't good enough.
My brother though that I wouldn't notice that he'd swapped the bulbs in my tail lights with LEDs.
One thing that I love about incandescent light is actual warmth, not just "warm white."
As to the "power hungry" part.
LED bulbs may run cooler but, in a house, you end up paying for the difference either way, in the winter, with your heating bill.
I tested it.
2022-23, I ran 100% LED bulbs from November to March.
Then, I ran 100% incandescent bulbs from November 2023 to March of this year.
The electric bills were the same amount, exactly.
All of the lights were on timers, set to turn on at 04:30, shut off at 08:30, turn on at 16:30 and turn off at 21:30.
There was no difference in power usage, the meter showed the same data between LED and incandescent bulbs.
The lower heat of the LED bulbs made the heater run just that much longer.
Considering that the house is foam insulated, it was a fairly accurate test with me gone for 6-9 months as an OTR truck driver.
No one went in or out of the house.
