I had a condensation problem in my left headlight and I decided to get a replacement. The one i bought (from ebay) didn’t have that cap at the top of the assembly that you can usually accesss from the engine bay. Instead there is just a sealed circle..Is that access from the cap necessary to install all of the bulbs/modules? or is it just a convenience thing that I can do without? Thanks for any help..
