Q1What changed6 changes
“On” time and “off” time for groups of flashes (paras. 1.4. and 1.5.)
For groups of several flashes, the “on” time runs from the beginning of the group's first flash to the end of its last flash. Before this supplement, paragraph 1.4. had no sentence about groups of flashes. For groups of several flashes, the “off” time runs from the end of a group's last flash until the next group's first flash begins. Before this supplement, the “off” time was evaluated from the last flash of the group to the first flash of the next group.
References in paragraphs 1.3. and 2.2.5.
Paragraph 1.3. now refers to Annex 5, para. 6 instead of Annex 5, para. 5. Paragraph 2.2.5. now refers to tests according to paragraph 5.6. instead of paragraph 5.5.
Table in Annex 5, paragraph 7.1.
The table in Annex 5, paragraph 7.1. now reads “Colour blue, amber or red” instead of “Colour blue or amber”. It also reads “Rotating system or flashing light sources” instead of “rotating system or flash light sources”. The colon at the end of paragraph 7.1. is deleted.

- GRE, 82nd session and 83rd session (October 2020)
Reasons
According to the proposal, the definition of the “on” time is not adapted to the case where a single flash consists of several flashes. It can be interpreted as a sum of only the “on” time of each flash in the group, without the gaps between flashes. The amendment aims to clarify the definition and to avoid interpretation problems.

“The current definition is not adapted to the case where a single flash consists of several flashes.”
“It can be interpreted, that it should be a sum of only the “on” time of each flash in the group (omitting the gaps between flashes).”
“The amendment aims to clarify the definition and to avoid interpretation problems.”
With the amendment, the definition of the “on” time is similar to the definition of the “off” time and considers a group of flashes. In case of several flashes, it is clear where to start and finish the calculation for the “on” and “off” time.
