Proposal to introduce provisions for triangular retro-reflectors of Class IIIB.

The amendment to paragraph 2.9.3. of Regulation No. 48 (Supplement 3 to the 02 series of amendments) introduced into the definition of the illuminating surface of a retro-reflector the reference to the declaration of this surface by the applicant during type approval of the device. This proposal amends UN R3 to provide for this procedure.
