They don't.
The old dynamo powered standard incandescent rear light bulb was 6V-0.1A or 0.6 watts.
New red rear LED light bulbs are 1 watt or low power white light bulbs are 0.5 watts.
So no real power saving.
What they do is throw out a lot more light for the same power used as less power is lost to heat.
Luck ........
