Hi can anyone confirm the screw thread size for the 4 screws that hold the lens on

I have new screws but one female thread is crossed so I want to retap it

Thanks steve

get yourself a set of BA thread taps … or at least the one which is the corresponding size

stand corrected ! I thought all small sizes were BA . 6/32 UNC for the rear lights?

No 4 BA thread for front and rear lights

Which kind of rear light is the Lucas 1807? (Should that be L807?)
If it’s the S4 / Sprint rear light it takes 6.32 UNC x 1??. At least that’s what fitted perfectly when I once renewed them, not 4BA.
PS if you’re replacing the screws it’s a good idea to use stainless steel cap head screws which are much easier to unscrew when you need to remove them years later.
