peak, summit
嶺 centers on the highest point of a mountain: a peak or summit. It is used for literal mountain tops and can extend to figurative high points.
嶺 combines 山 (mountain) with 領, which likely contributes the sound and the idea of a commanding high place. The exact historical development is uncertain.
A mountain 山 with a commanding presence 領 at the top: the peak that overlooks everything below.
For レイ, picture a ray of sunlight hitting the summit first at dawn: ray -> レイ, and the peak catches the light.
