Anybody know what year/month?  I'm referring to non-Ghia models here, as I gather they used square lights since the introduction of the MkII.  Incidentally, anybody know when was the MkII introduced exactly?
 
Thanks.

OK, this might have the answer to one of my own questions:

Based on the model codes listed it looks like it went from round to square headlights in Dec '78.

I have had half a dozen escorts of the last 2 years, and i have two 79 models, one with the round headlight and the blue oval badge, and one has a square head lights. then i also have a 80 model with the square head light front. so i would be guessing it would agree with flighter and say late 78 or in 79.

Is it  not when they went fron Mk2 escort to the BC code with the introduction of the 2 litre motor option

No. I had a 78 BC escort with round headlights. Also had a 75, 76, 77 and 79. Only the 79 GL had square headlights.

Yes Steve your right the first 2 litre Rally packs had round lights
78 is about the mark then

My 79 GL has round head lights.

and my 79 and 80 xl have square lights

Always thought it was the May 79 update that witnessed the conversion from round to square

Sounds right. It happened the same time that they deleted a whole stack of interior colour options from the range.
