LED refrigerator bulbs are already a thing; bought one recently by accident, when looking for a very low power/low brightness for a bed side table.

Those, apparently, are no longer a concern.

Screw in LED bulbs with built in brightness and color control, that you can command from a phone application or through a conventional remote control, are already common, thus rendering conventional dimmers obsolete.

Why keep those? To my very limited knowledge, dimmers can require expensive and extensive installation.

I have seen LED traffic lights with built in anti frost measures and the expenditure to have those replaced is not a good argument to keep that particular use of incandescent lamps around.

LED low power requirements, paired with their long service life, enables traffic lights to be independent from the power grid, through the use of solar panels and batteries, keeping it working even when severe weather disrupts energy distribution. LEDs are also brighter and easier to see from afar.

There may be very particular cases where incandescent bulbs still do not have an alternative but to say they are irreplaceable is a disservice.

I'm not trying to be dismissive, I'm trying to be demanding.
