Light Crystal

The Light Crystal is a crystal located in the forehead of some Ultra in Tiga's universe. Note that term 'Light Crystal' is not official but is used for easy understanding.

Nature
First seen on Ultraman Tiga, the "Tiga Crystal" is always located on the forehead of certain Ultras in the Tiga Universe. Since Tiga gained the power to type change by absorbing the attacks of other Dark Ultras, it can be assumed his crystal regulates the powers within his body, altering the ratios to change his type. It is similar to the Beam Lamp seen on some Ultras, such as Ultraseven.

Difference between Type and Mode
Despite the similarities, Type Switch is different from Mode change. Mode change is mainly an altering of the Ultra's nature to give them more abilities and/or greater combat prowess. An example of this Cosmos' Corona mode, which is for combat while his normal form revolves around peaceful solutions to conflict. Mebius' Brave and Burning Brave mode, made him more powerful. Despite being called modes Zero's StrongCorona and LunaMiracle Modes have more in common with type change than standard mode changes.

Type change does just as it's name implies, changes the type of the Ultra, red Ultras are known for having bodies better suited to physical combat, while Blue Ultra abilities lean towards speed and/or mental abilities. Note that most of the Ultras who type change, Tiga, Dyna and Zero who gained his previously mentioned forms from Dyna, are red and blue Ultras. Type change partially alters their bodies to follow the example of Ultra colors. Red forms are more oriented towards physical combat, becoming much stronger, while Blue forms are faster and generally have more varied light abilities.
