The Task Force on LED Substitutes and Retrofits reports on establishing a type-approval framework for LED replacements to enable safe technology transition from incandescent to LED lighting for cars-in-use. Step 1 completion has resulted in growing LED replacement category sheets in RE5, with national and UN approvals enabled. Step 2 requires improved market surveillance, as unsafe non-approved products reach roads and some R37-approved products show non-compliance. The task force proposes waiting for front fog cycle completion and applying lessons learnt before enforcing the high beam package, addressing keying deficiencies and inadequate warnings on unapproved products. Market surveillance control points span approval, import, point of sales, PTI, and roadside enforcement.
