Lifelight, or Cultivation's Light, is perhaps the rarest of the three pure Lights. Some of it can be found in the [[Valley]], in the form of green mist.{{wob ref|12207}} [[Lift]] is uniquely able to produce it by metabolizing food,{{book ref|sa4|60}} but no other ways of obtaining it are currently known. It appears very similar to Stormlight, a nearly pure white light, but where Stormlight has a slight blue tint, Lifelight has a slight green one. When its illumination is split through a prism, it produces a rainbow with a larger green band.{{book ref|sa4|65}} Its rhythm is stark and staccato, but it builds. Lifelight shares Stormlight's effect on plants but to a superior degree, stimulating their growth when combined with the proper rhythm.{{book ref|sa4|76}}

Towerlight is the very substance of the spren known as the [[Sibling]], and as they are the child of Honor and Cultivation, so is Towerlight the product of the melding of these two Shards' Investitures, tones, and rhythms. It can only be created by the [[Sibling]] and their [[Bondsmith]], though the imprisonment of [[Ba-Ado-Mishram]] rendered them unable to produce more than small amounts - enough to power only the most essential of [[Urithiru]]'s fabrials[[fabrial]]s;{{book ref|sa4|69}} a deficiency that appears to have ended when [[Navani Kholin]] became the Sibling's current Bondsmith. A key factor in the creation of Towerlight is the Sibling's ability to hear both of their parents' songs - Cultivation's, which they could hear and sing on their own, and Honor's, which Navani had to provide for them.{{book ref|sa4|110}} Because of this, it is unclear whether the Sibling is truly "healed", or losing the bond - and Navani - would mean that they lose Towerlight once again.

Unlike Towerlight, which has been known to humans and singers alike for millennia (even if knowledge of it was largely lost on Roshar after the [[Recreance]]), Warlight - the hybrid Light of Honor and Odium - is a recent discovery, one that even renowned singer scholars like [[Raboniel]] thought an impossibility. During the occupation of Urithiru Navani discovers that a human and a singer (or at least she and Raboniel) can create Warlight by allowing Stormlight and Voidlight to combine inside a gem made to vibrate to the Rhythm of War - a rhythm created by the harmony of Navani singing Honor's song and Raboniel singing Odium's; a rhythm Raboniel didn't know existed prior to these events,{{book ref|sa4|76}} and whose emotional influence she notes will be of particular interest to [[El]].{{epigraph ref|sa4|59}}

The existence of an Odium and Cultivation hybrid Light hasn't been confirmed, but [[Venli]] successfully attunes a rhythm of these two Shards, so a corresponding Light is likely.{{book ref|sa4|83}}
