Some Ultra hosts/in human form do not use transformation items and instead transform by pure will. This ability also extends to Ultras Hosts with transformation items as they have been shown to activate them by force of will. The advantage of this ability is that the Ultra can transform their host when they do not have the ability to do so themselves, such as the case of falling unconscious.
The fact that Ultraman Hikari used this to transform, he had temporarily relinquished his transformation item the Knight Brace to Mebius) implies that all Ultra possess this ability. Even at the end of the series, Ultraman Mebius transformed this way instead of his usual method using the Mebius Brace. This implies this ability is not limited to a few Ultras and transformation items may simply be a thing of convenience.
