The present disclosure relates to a stretch/bent roof rail apparatus for use on an exterior body surface of a vehicle. The apparatus may have a roof rail having a body portion, with the body portion having an opening. A housing assembly is adapted to fit at least partially within the opening in the body portion and has a support cradle and a cap. The support cradle and the cap may be configured to be secured to one another. The housing assembly may further being configured to enable an electrically powered component to be arranged within the cap and provided with an unobstructed line of sight outwardly from the roof rail body portion. The support cradle may have a footprint generally in accordance with the roof rail and configured to fit substantially completely within the roof rail. This helps to support the electrically powered component such that the roof rail, the housing assembly, and the electrically powered component form a unitary assembly when assembled together.
