Abstract

An LED retrofit lamp includes a centering ring with alignment features, which define: a mounting position of the lamp within a vehicle reflector, a reference axis, a reference direction along the reference axis from a base to a top end of the lamp, and a tolerance box intersecting the reference axis and extending axially along the reference direction from a tolerance box base-side end to a tolerance box top-side end. The lamp also includes an arrangement that emits light transversal to the reference axis and has a light-emitting area that extends axially from an LED base-side end to an LED top-side end. The LED base-side end has an axial distance of at least 0.1 mm from the tolerance box base-side end in the reference direction, and the LED top-side end has an axial distance of at most 1.5 mm from the tolerance box top-side end in the reference direction.
