Headlights for 1986 911

Pelican Parts sells a Hella H4 headlight conversion kit  (Hella 002395991)  for 911's. While the note in the listing states "Replaces 7" Round Sealed Beam Headlight. Includes- (Qty.) (1) headlight (1) bulb. "OFF-ROAD USE ONLY" Not Certified for Highway Use." The rep assures that the note refers to a DOT approval that has nothing to do with the lights being inappropriate replacements for the original 911 lights.  Is there anything wrong with using these lights?

Also,  I am replacing the rubber headlamp rim seal (with Porsche part #911-631-115-02-OEM) and having removed and replaced the headlight shroud (trim piece with one screw in the bottom) in the past without any issue, I am now having a problem fitting the shrouds back on and tightening the screws.  The screws will not tighten even with the holes lined up properly. Is there a trick that I'm missing this time? Could it be that I'm incorrectly installing the rubber rim seal?

Thank you.
