The ring forms an excellent fit between the base of a modern bulb and the bulb housing meaning that the bulb is held securely without further modification being necessary.
2 step ring to ensure that your new bulb seats properly in the housing.
Can be used with our H4 LED Headlight bulbs for that ultimate upgrade.
