in assemblies they appear to be bright enough... see:

Does semiconductor LEDs work near with strobe flashtubes (HIGH
VOLTAGE)??? I am looking ElectroMagneticCompatibility.

Anyone experiences or recommendations, please?

Can't answer the question about interoperability with flashtubes, but
these
are starting to show up for marine use, however there's nowhere near
bright enough (at least the marine ones) to meet the Part 23 brightness
requirement for position lights.

You need up to 40 candela over 110 degrees horizontal and +/- 90
degrees vertical. Can be done I guess, but can't find anything canned
that has that kind of specs.
