Where to look at while doing landing flap verification and check 3 times at ldg CL

[Uplinker]

I was only on the B737 for a season and I can't fully remember now but there is a section on the overhead panel with a pattern of lights to indicate the leading edge flaps, as Boeing call them, are out.

I think that also indicated the actual (trailing edge) flap deployment as well ? I could be wrong, but that might be your third indicator.
