UN R48 Supplement 3 (08 series) · UNECE Regulation No. 48 (ECE R48) — Uniform provisions concerning the approval of vehicles with regard to the installation of lighting and light-signalling devices.
UN R48 — Supplement 3 to the 08 series of amendments
Supplement 2 → 3
- What changed
- Paragraphs 6.4.8., 6.11.8., 6.12.8., 6.18.8. and 6.20.8. now say that a tell-tale indicating failure is mandatory if required by the component regulation.
- Paragraph 5.5.4. now says that the requirement for substantially identical photometric characteristics does not apply to a matched pair of a function and/or an AFS.
- In paragraphs 6.2.9.2. and 6.2.9.3., the objective luminous flux of more than 2,000 lumens now applies “for each headlamp”.
- Why
- Component UN Regulations allow a tell-tale indicating failure for some lamps, and the proposer changed UN Regulation No. 48 to be compliant with them.
- Headlamps approved under the 01 series of amendments to UN Regulation No. 149 may be type-approved as matched pairs.
- Other changes correct mistakes in the text, for example text that was missing and wrong references.
Q1What changed57 changes
Tell-tales (paras. 6.1.8., 6.2.8.2., 6.3.8., 6.4.8., 6.7.8., 6.9.8. to 6.12.8., 6.18.8., 6.20.8. and Annex 1)
Paragraphs 6.4.8., 6.11.8., 6.12.8., 6.18.8. and 6.20.8. now say that a tell-tale indicating failure is mandatory if required by the component regulation. Paragraph 6.7.8. no longer has the sentence “Where the above tell-tale is fitted, this tell-tale shall be an operating tell-tale …”. Paragraphs 6.3.8. and 6.11.8. no longer have the words “An independent non-flashing warning light.”. Paragraphs 6.1.8., 6.3.8., 6.9.8., 6.10.8., 6.11.8. and 6.12.8. now say “Closed-circuit tell-tale” instead of “Circuit-closed tell-tale”. Paragraph 6.2.8.2. now calls the mandatory visual tell-tale a “visual failure tell-tale”. New Annex 1 items 9.2.1., 9.4.1., 9.13.1., 9.14.1., 9.20.1. and 9.23.1. ask if a tell-tale indicating failure, as required by component regulation, is fitted.
Matched pairs (paras. 5.5.3. and 5.5.4.)
Paragraph 5.5.3. now contains only the requirement to satisfy the same colorimetric requirements. The requirement for substantially identical photometric characteristics is now only in paragraph 5.5.4. Paragraph 5.5.4. now says that this requirement does not apply to a matched pair of a function and/or an AFS. Before this supplement, the exception in paragraph 5.5.3. named a matched pair of Class F3 front fog lamps.
Direction indicators and side-marker lamps (paras. 6.5.7. and 6.18.9.)
In paragraph 6.5.7., a direction indicator capable of being activated in different modes (static or sequential) must not switch between both modes once activated. Paragraph 6.5.7. also covers two optional lamps (category 2a or 2b) installed on vehicles in categories M2, M3, N2 or N3. These lamps must be operated in the same mode as the other mandatory rear direction indicator lamps (category 2a or 2b). Paragraph 6.18.9. now covers an optional side-marker lamp grouped or combined with a position lamp that is reciprocally incorporated or grouped with the direction indicator. The side-marker lamp on the relevant side may then be switched OFF during the entire period (both ON and OFF cycle) of direction indicator activation.
Park condition of a trailer, additional lamps and Annex 6 measurement (paras. 2.3.11.2., 5.21.1. and Annex 6, para. 5.4.3.)
New paragraph 2.3.11.2. defines the park condition of a trailer connected to a drawing motor vehicle in the condition of paragraph 2.3.11.1. In this park condition, the movable components of the trailer are also in the normal position(s) as defined in paragraph 2.3.9. Paragraph 5.21.1. on additional lamps for a movable component now ends with the word “or”. Annex 6, paragraph 5.4.3. covers vehicles with non-conventional suspension, where the propulsion system has to be running. It now adds: “Before making any measurement wait until the vehicle has assumed its final attitude with the engine running.”
Luminous flux for each dipped-beam headlamp (paras. 6.2.9.1. to 6.2.9.4.)
Paragraph 6.2.9.2. covers dipped-beam headlamps with a light source or LED module(s) producing the principal dipped-beam. In this paragraph, “2,000 lumens” now applies to the total objective luminous flux for each headlamp. Above this value, these headlamps must only be installed in conjunction with the installation of headlamp cleaning device(s) according to Regulation No. 45. Before this supplement, the paragraph did not have the words “for each headlamp”. Paragraph 6.2.9.3. also now refers to the objective luminous flux for each headlamp. Paragraph 6.2.9.4. now says “UN Regulations Nos. 98, 112 or 149” instead of “UN Regulation Nos. 98, 112 or 149”.
References to other paragraphs and UN Regulations (paras. 6.1.8.1., 6.1.9.3.1. to 6.1.9.3.5., 6.20., 6.22.7.4.3. and 6.22.9.1.)
Paragraphs 6.1.8.1., 6.1.9.3.1., 6.1.9.3.1.1., 6.1.9.3.2., 6.1.9.3.4.(a) and 6.1.9.3.5. now refer to paragraph 6.1.7.2. instead of paragraph 6.1.7.1. Paragraph 6.20. now says “Cornering lamp (UN Regulation No. 119 or 149)” instead of “Cornering lamp (UN Regulation No. 119 or [RID])”. Paragraph 6.22.7.4.3.(b) now refers to UN Regulation No. 149, Table 14 instead of UN Regulation No. [RID], Table 14. Paragraph 6.22.9.1. now refers to item 9.2.3. of the communication form of UN Regulation No. 123 instead of item 9.3. For UN Regulation No. 149, the paragraph names item 9.3.2.3. of the 00 series of amendments and item 9.2.2.3. of the 01 series of amendments. Before, it named item 9.3.3. in Annex 1 to UN Regulation No. 149.
Deleted footnote 13 and wording changes (paras. 5.9.2., 6.3.5., 6.3.6.1.1., 6.5.8., 6.19., 6.24.9.1., 6.24.9.2. and Annex 2)
Footnote 13 is deleted, together with its references in paragraphs 6.3.5., 6.3.6.1.1. and 6.5.8. The footnote was about new vehicle types which do not comply with this provision. It said they may continue to be approved until 18 months after the entry into force of Supplement 4 to the 03 series of amendments. In paragraphs 6.19. and 6.24.9.2., “Day-time” and “day time” become “Daytime” and “daytime”. Paragraph 5.9.2.(c) now says “the lamp” instead of “the lamps”. In Annex 2, one approval mark figure changes, and the text now says “E4” instead of “E 4”.
Q2Why it changed
- Proposed by
- Experts from the International Automotive Lighting and Light-Signalling Expert Group (GTB); expert from the International Organization of Motor Vehicle Manufacturers (OICA); expert from China
- Working party
- GRE, 87th session (October 2022)
Reasons
Component UN Regulations allow a tell-tale indicating failure, for example for reversing lamps and rear fog-lamps. The proposer changed the tell-tale paragraphs of UN Regulation No. 48 to be compliant with the component UN Regulations. The tell-tale items in Annex 1 were missing for dipped-beam, reversing lamps, rear fog-lamps, parking lamps, side marker lamps and cornering lamps.
Sources (3)
“For reversing lamps, we have the possibility in component UN Regulations Nos. 23 and 148 to have a tell-tale indicating failure. We have modified the requirement in paragraph 6.4.8. to be compliant with the component UN Regulations.”
“For rear fog-lamps, we have the possibility in component UN Regulations Nos. 38 and 148 to have a tell-tale indicating failure.”
“We have modified Annex 1 and added tell-tale requirements when requested by the component requirements. They were missing for dipped-beam, reversing lamps, rear fog-lamps, parking lamps, side marker lamps and cornering lamps.”
The proposer used the wording “closed-circuit” instead of “circuit closed”, to have the same wording in the definition and in the requirements. For front and rear fog-lamps, the proposer saw no reason why the tell-tale should be an independent non-flashing warning light. For stop lamps, the proposer removed the requirement about an operating tell-tale when a tell-tale is required by component regulations.
Sources (3)
“In order to have the same wording for the definition in paragraph 2 (sub-paragraph 2.3.6.) and the requirements in paragraph 6, we have unified the wording “closed-circuit” instead of “circuit closed”.”
“There is no reason why this should be an independent non-flashing warning light.”
“For stop lamps, we have removed the requirement about an operating tell-tale when tell-tale is required by component regulations”
Headlamps approved under the 01 series of amendments to UN Regulation No. 149 may be type-approved as matched pairs. For this reason, paragraph 5.5.4. had to exempt from symmetry not only the photometry of matched pair front fog lamps, but all matched pair functions. AFS lamps, for which photometric requirements of a lighting function may apply to half of the sum, also need this exemption. The requirement for “substantially identical photometric characteristics” was in both paragraphs 5.5.3. and 5.5.4.

“Headlamps approved under the 01 series of amendments to UN Regulation No. 149 may be type-approved as matched pairs.”
“It has become necessary to change the requirement of paragraph 5.5.4. of UN Regulation No. 48, exempting of symmetry not only the photometry of a matched pair front fog lamps, but all matched pair functions.”
“for which photometric requirements of a lighting function may apply to half-of-the-sum, need also to be exempted of symmetry for the photometric values.”
“the requirement regarding “substantially identical photometric characteristics” is doubled (contained in both paragraphs 5.5.3. and 5.5.4.).”
Paragraph 2.3.11.2. was missing; it was in Supplement 12 to the 06 series of amendments. Some parts of paragraphs 6.5.7. and 6.18.9. had been omitted by mistake. The automatic main-beam provisions referred to the wrong paragraph 6.1.7.1. instead of 6.1.7.2. Footnote 13 was deleted because its content was obsolete.

“In paragraph 2.3.11., subparagraph 2.3.11.2. was missing (it was originally present in Supplement 12 to the 06 series of amendments to UN Regulation No. 48).”
“re-inserted some parts of paragraphs 6.5.7. and 6.18.9. that had been previously omitted by mistake”
“4. In paragraphs 6.1.8. and 6.1.9., the automatic high beam activation refers to the wrong paragraph 6.1.7.1. instead of 6.1.7.2.”
“14. Deletion of footnote 13 in paragraphs 6.3.5., 6.3.6.1.1., 6.5.8. is due to the footnote content being obsolete.”
The word “or” at the end of paragraph 5.21.1. was removed by mistake in earlier proposals. The word “or” permits an alternative test process, so its removal also removed this alternative test route.
Sources (2)
“The corrigendum returns the word “or” to the end of paragraph 5.21.1., as it was removed by mistake when the proposals ECE/TRANS/WP.29/GRE/2019/29 and ECE/TRANS/WP.29/2019/36 were made.”
“As the word “or” permits an alternative test process, its removal by default removes this alternative test route.”
