Status report on the work of TF-LUPC following two meetings since GRE-94. The group is improving a proposal on lamps under parked conditions, with open issues remaining on energy status indicators, lamp test mode, and related specifications. A final proposal is planned for submission to GRE-96 in April 2027 for integration into the 10 series of amendments to UN R48.

The Task Force on Lamps Under Parked Conditions will hold its 12th session as a hybrid meeting in Tokyo on 11 September 2026. The agenda includes discussion of Terms of Reference to modify the timeline, continuation of questionnaire discussion, and proposal for modification of UN R48 regarding lamp test modes and Energy Indicators for M₁ and N₁ vehicle categories. The session will also address follow-up and action items, review of existing Regulations and Standards, any other business, and confirmation of the next meeting.

OICA proposes:

• Amend the heading of para. 2.11.5. to clarify that additional colours are introduced specifically for energy status indication,
• Add colour requirements in para. 5.15. permitting white, amber, red, selective-yellow, indicator blue, or indicator green for energy status indicators, with indicator blue and indicator green reserved for charging, discharging, or scheduling of energy transfer to or from the rechargeable electrical energy storage system,
• Replace multiple charging connector provisions in para. 6.29.9.1. to specify conditions for energy status indicator activation,
• Add para. 6.29.9.1.1. permitting independent activation of multiple energy status indicators,
• Insert para. 6.29.9.6. requiring vehicle manufacturers to declare intended use of indicator blue and indicator green in the information document,
• Add para. 6.29.9.2. establishing observation area intensity requirements and limiting intensity outside this area to 140 cd,
• Amend Annex 14 to include energy status indicators.

Terms of reference and rules of procedure for the Task Force on Lamps Under Parked Conditions (TF-LUPC). TF-LUPC shall review the requirements of the current suite of lamps under parked conditions and develop proposals within the framework of UN R48 pertaining to Energy Indicator and Lamp test mode. The task force is open to all GRE participants. Two Co-Chairs (Japan/Netherlands) and a Secretary (OICA) shall manage it. Decisions shall be reached by consensus. STEP 2 aims to present an informal document at GRE’s ninety-fifth session in October 2026 and a formal document at the ninety-sixth session in April 2027 for submission to WP.29 as part of the 10 series of amendments.

Draft amendments concerning lamps under parked conditions presented in a consolidated revision of UN R48.

Draft report of the 12th session of the Task Force on Lamps Under Parked Conditions. Discussion of a proposal for modification of UN R48 covered additional colours for energy indicators, with concerns raised regarding blue indicators and police signals, the number of indicators permitted per connector, distinction between passenger cars and trucks/buses, and observation angles and intensities. Agreement was reached on the size of apparent surface for indicators. The group decided to continue discussion on lamp test mode at the next session and to send a status report, revised Terms of Reference, and an informal proposal to the 95th session of GRE.
