Abstract: A headlamp assembly includes a housing and a lens. The housing forms an interior space to receive a lamp. A free or peripheral edge of the housing has a channel sized to receive an edge of the lens for attachment and sealing purposes. The channel includes breakaway portions formed at spaced apart intervals. The breakaway portions are spaced to align with spaced apart connectors extending from the edge of the lens. When mating the housing and lens, the channel is filled with adhesive and the free edge of the housing is joined with the edge of the lens. The connectors penetrate the breakaway portion as part of the joining step to interconnect the housing and lens. The connectors may be shaped to snap fit with the housing after penetration through the breakaway portion. The breakaway portion may be formed as part of the base of the channel or can be formed in a recess within the base.
