item 8 is "8338566" shell electrical co(nnector)
found this website tonight-
Amerline - Single Wire Waterproof Connectors
which has a table of the different connector assemblies and individual parts.
Tells us that the 14 gauge version of the female connector assembly is needed. (female shell, male connector...)
Which is "MS27142-2" or "8338565"
Which is this page at Erik's
Rubber Shell Connectors (qty 10) MS27142-2
Which are the one I know I buy most often !
(This ought to leave lots of search terms to keep the moderators happy !)
Of course, if your light is like mine, the male rubber part usually pulls off the light with the female connector, leaving the female connector sticking out and looking nothing like any of the connector assemblies. I have, so far, been able to just push the whole mess back together, but will probably need a new light at some point.
