It is a 'requirement'
Here is one of what has to be many hundreds of
publications on the topic:
https://tinyurl.com/mrwzfn64
The real-world is replete with
anecdotal recitations of outcomes arising
from inability to reach a particular control.
Or perhaps the outcome was strongly influenced
by training i.e. recognition and timely
action to mitigation of an anomalous
condition.
Human factors has always been high if not
at the top of the list for risk mitigation.
Individuals with a propensity for worrying
about risks are noteworthy for their desire
to regulate, legislate, design or educate
toward the utopian, risk-free condition.
Sometimes, those efforts have a good
cost/benefit ratio . . . but it's
impossible to address ALL human shortcomings
that go to increased risk. Recall the
fuel selector location on John Denver's
Long-Ez, Dan Lloyd's under-crimped
power distribution terminals, and crews
of the 737MAX aircraft who (when
presented with an un-commanded pitch down on
their aircraft) were TRAINED to search
the emergency procedures check list
for a 'solution'.
Yeah, it seems like a no-brainer that
all critical controls should be suitably
accessible to the pilot under normal and
abnormal conditions of flight.
But it's important for YOU to do your
own FMEA on configuration decisions for
your project. Sitting in the cabin of
your unfinished airplane doing your
'Walter Mitty thing' need not be a
frivilous exercise. Astronauts spent
hours in their simulators practicing,
refining and documenting response to
every possible operational scenario.
Even so, their emergency procedures
manuals were decidedly silent when
it came to dealing with a failed oxygen
system blew out the side of their
spacecraft.
Do the best you know how to do and don't
hesitate to exploit the knowledge and
experience of your peers.

I used this one and am pleased with it but I am not flying yet.

Subject: AeroElectric-List: Aeroflash tail light & strobe
Hi everyone,
A long time ago I installed an Aeroflash combination tail light strobe
assembly on my experimental aircraft. I need to replace it and
I=99d appreciate some advice on what my options are.
Thanks, Paul

I have Hakko FX-888D. Seems weaker than it's 65W. The Hakka tips are ferrou
s throughout per my magnet and filing a notch in one finds no copper.
I=92m gonna try Amazon "ShineNow Quality T18 Soldering Tips". eBay descrip
tion is more complete, says "oxygen free pure copper as base, plated with i
ron, coated with nichrome plating and pretinned with lead free solder"
Will report back.
