The decision follows the full assembly condition, confirmed fault, parts and accepted scope.
For damaged outer material, compare surface restoration with lens replacement. For a dim, yellow or failed DRL, identify the internal lighting fault. For persistent droplets or standing water, investigate the ingress path. Broken housings need a separate assessment of structure, available replacement parts and reusable internals.
A full refurbishment may retain serviceable internals within a new housing and outer lens; complete assembly replacement remains an option when the retained parts or proposed repair are not viable. These are separate decisions, not stages that every customer must buy.
