While shrouds are non-essential, they play a large role in the fit-and-finish of your headlight retrofit! They are simply designed to enhance the look of the conversion. Shrouds mount to the front face of the projector to hide from view not only the raw body of the projector itself, but also any hardware or construction materials used to mount it.
These shrouds are made to fit 3" projectors like the D2S series but WILL fit 2.5" like the H1 series projectors with SPACER RINGS (found in drop down)!
