From the FAA FSIMS, their inhouse guidance to be a Fed -
When the 61.75 certificate is issued it will have the following
“ISSUED ON THE BASIS OF AND VALID ONLY WHEN ACCOMPANIED BY [NAME OF COUNTRY] PILOT LICENSE NO. [NUMBER FROM FOREIGN PILOT LICENSE]. ALL LIMITATIONS AND RESTRICTIONS ON THE [NAME OF COUNTRY] PILOT LICENSE APPLY”
And further
"D. Night Restriction. Some foreign pilot licenses contain a restriction that prohibits the person from operating an aircraft at night. As an example, some foreign CAAs require their citizens to hold an instrument rating and/or a night flying privilege to operate an aircraft at night. That person must also comply with that night operating restriction of his or her foreign pilot license when exercising the privileges of the § 61.75 U.S. pilot certificate (refer to § 61.75(e)(3)). To clarify, while the FAA may not remove the night flying restriction, it is permissible for a foreign pilot who receives a U.S. pilot certificate on the basis of the person’s foreign pilot license to accomplish the required night flying training (for the appropriate grade level of U.S. pilot certificate held) from a holder of an FAA flight instructor certificate, and receive a solo endorsement to exercise night flying privileges on his or her U.S. pilot certificate."
Regarding the validity of the verification letter
"When verification is received from a foreign CAA, the applicant will receive written notification that a copy of the verification of authenticity of the foreign pilot license has been forwarded to the designated FSDO in the applicant’s request. The verification of authenticity of the foreign pilot license is valid for 6 calendar‑months."
Looking at the current 8900.2C I don't see a section 5-382. However there is a whole Section 20 which talks about issuing a 61.75 certificate. The first item in the Procedures section is "126. Procedures.
a. Applicant Arrives at the Designee’s Location. Determine whether the managing FAA office has received the verification of authenticity letter from the Airmen Certification Branch."
