(EFI) is the intensity of the light corrected for the length of the flash and is
determined by the formula:
EFI = I × (tc ¥ ti) / 0.2 + (tc ¥ ti)
Where:

I is the measured intensity of the fixed
beam,
tc is the contact closure time in seconds, (0.33 for this S-O-S signal), and
ti is the incandescence time of the
lamp in seconds.
(d) An electric light which meets the
requirements of either paragraph (a) or
(b) of this section need not, if capable
of operating in both manners, meet the
requirements of the other paragraph.
§ 161.013–7

Signal requirements.

(a) An electric light must have a
flash characteristic of the International Morse Code for S-O-S and,
under design conditions,
(1) Each short flash must have a duration of 1⁄3 second;
(2) Each long flash must have a duration of 1 second;
(3) The dark period between each
short flash must have a duration of 1⁄3
second;
(4) The dark period between each
long flash must have a duration of 1⁄3
second;
(5) The dark period between each letter must have a duration of 2 seconds;
(6) The dark period between each
S-O-S signal must have a duration of 3
seconds.

§ 161.013–9

46 CFR Ch. I (10–1–98 Edition)

(b) The flash characteristics described in paragraph (a) must be produced automatically when the signal is
activated.
§ 161.013–9 Independent power source.
(a) Each independent power source
must be capable of powering the light
so that it meets the requirements of
§ 161.013–3(a)(1) and emits a recognizable flash characteristic of the International Morse Code for S-O-S at a rate
of between 3 and 5 times per minute
after six hours of continuous display of
the signal.
(b) If the independent power source is
rechargeable, it must have a waterproof recharger designed for marine
use.
(c) If the independent power source
requires external water to form an
electrolyte, it must operate in sea
water and fresh water.
§ 161.013–11 Prototype test.
(a) Each manufacturer must test a
prototype light identical to the lights
to be certified prior to the labeling required by § 161.013–13.
(b) If the prototype light fails to
meet any of the general performance
requirements of § 161.013–3 the lights
must not be certified under this subpart.
(c) Each manufacturer must:
(1) Forward the test results within 30
days to the Commandant (G–MSE), U.
S. Coast Guard, Washington, DC 20593–
0001; and
(2) Retain records of the test results
for at least 5 years, or as long as the
light is manufactured and certified,
whichever is longer.

certification and labeling.
(a) Each electric light intended as a
Night Visual Distress Signal required
by 33 CFR part 175 must be certified by
the manufacturer as complying with
the requirements of this subpart.
(b) Each electric light must be legibly and indelibly marked with:
(1) Manufacturer’s name;
(2) Replacement battery type;

(3) Lamp size; and
(4) The following words—
‘‘Night Visual Distress Signal for
Boats Complies with U. S. Coast Guard
Requirements in 46 CFR 161.013. For
Emergency Use Only.’’
(c) If an electric light is designed for
use with dry cell batteries the label
must advise the consumer on the battery replacement schedule which under
normal conditions would maintain performance requirements of § 161.013–3.
§ 161.013–17 Manufacturer notification.
Each manufacturer certifying lights
in accordance with the specifications
of this subpart must send written notice to the Commandant (G–MSE), U.
S. Coast Guard, Washington, DC 20593–
0001 within 30 days after first certifying
them, and send a new notice every five
years thereafter as long as it certifies
lights.
