I am probably going to replace my headlight assemblies on my 2008 HR Neptune due to a cracked lens. About 10 years ago a factory tech told me that they are the same as used on a particular make and model automobile/truck from 2007-2008. Unfortunately I can't remember the auto/truck he referenced. Anyone have an idea? I know that there is probably some DOT id number stamped somewhere on the assembly but no luck finding without pulling out he assembly I think. Thanks. Joe
