Now you can easily model removed headlight and classification lights on your favorite diesels.  Many railroads changed their headlight/class light configuration over the years and almost always, the removed lights were patched with a scrap of metal.   This set includes numerous styles of common headlight patches for that special diesel project. - Product Key: •  Long Light Covers:  These will work on most diesel headlights (standard two-light cluster). •  Small Light Covers:  These light covers are perfect for classification lights.  We have provided a number of common styles that are not necessarily railroad specific.
