I know that they're supposed to be brighter than other kinds, and you need them to make white light, but what are some practical applications for them?

Emergency vehicles use them due to the fact you can see them from farther away, and they appear much brighter.

Brightness is all about energy. If you put the energy in, it is brighter. If you don't use as much energy, it is dimmer. Use it like you would another LED. It can indicate that a signal is present or missing. It can indicate that something is on or has occurred. It can do what you want. It can be used to make it harder to see stars at night...not advisable or fun. Have fun.

Technically they aren't brighter. They just appear brighter to the human eye since the human eye is more sensitive to shorter wavelengths, such as blue light.

Practical applications are anywhere you want a blue light.

People interested in aquariums use them to simulate moon lighting.
