A mounting assembly configured to attach a headlight to a vehicle includes a mounting bracket and a support member attachable to the mounting bracket. The mounting bracket includes a first portion and a second portion extending from the first portion. The first portion is configured for attachment to the vehicle, and the second portion includes a major surface defining a longitudinally curved saddle. The support member includes a base configured for attachment to a housing of the headlight and a curved seat configured to couple to the curved saddle of the mounting bracket. In this regard, the curved saddle and the curved seat are configured to have substantially complementary curvature such that the curved seat nests relative to the curved saddle. Longitudinal movement of the curved seat of the support member relative to the curved saddle of the mounting bracket permits a height adjustment of the headlight. A connector extends through an elongate bore in the second portion of the mounting bracket and connects to the support member to securely fix the relative positions of the support member and the mounting bracket.
