I was looking at new bulbs for my hatch what is the diff between diamond cut and regular headlight bulbs

 

sounds like marketing BS mumbo-jumbo to me.

*edit* everything I saw on a quick web search referring to "diamond-cut headlights" were those sealed-beam replacements that allow you to use regular halogen bulbs in them.

 

I searched aswell b4 posting, all i found was bs too

 

If you don't have sealed beam headlights now, then I don't think "diamond-cut" lights will work for you.
