The factory never used Lucas headlights on series B and they were all Miller and I have never come across a Lucas headlight on a works order form for a series B. Your bike Texas John shows the standard Miller lighting entry but in the remarks section mentions 7" lamp and so that will be the smaller Miller unit.
The way the build sheets were filled in usually was the basic build spec was filled in by office staff for the shop floor to follow, sort of like a recipe. Then as the bike was built then any alterations were either written in any spare gaps on the form or in the remarks area. This can usually be seen by the different handwriting and sometimes the different colour pen, details which you cannot see on black & white copies of the documents.
When it comes to the lights then for some unknow reason the same entry 94E (which is the 8" unit) was always written even after the smaller unit became standard. I assume the office staff initially filling in the form didn't know any better. Its the 7" or 8" comment which should be noted as that was what the assembler actually fitted and he didn't know what it was going to be until he opened the Miller box as it was all down to pot luck on what Miller had supplied on that day.
The first reference to 7" headlights I can see in the factory records is around begining of November 1947 and then there is a mixture of both 7" & 8" all the way through to the last 8" unit around March 1949 and around June 1949 they stopped recording the headlight size so by then the 8" unit must have completely stopped been provided by Miller.
