737 lighting
some other lights which may only be specific to our aircraft but i wouldnt have thoght so include - small circular escape slide illumination lights just aft of all 4 main deck doors approx half way up height of door, between the 2 overwing hatches on the -400 there is an escape light which is just above the lower edge of the hatch sills. I am not 100% sure but am fairly postive there is alos a leading edge/engine insp light fwd and above the wing root at the leading edge - i will check this this afternoon and get back to you.
Hope this is of some help
