Why Capless Wedge? The 501 bulb uses a capless wedge base that simply pushes into the socket - no twisting or bayonet action required. This makes installation quick and easy, especially in tight dashboard spaces. The wedge design also provides a secure friction fit.

Installation: Simply push the wedge base directly into the socket until fully seated. To remove, gently pull the bulb straight out. Always ensure the ignition is off before replacing bulbs. For exterior applications (sidelights, number plates), replace in pairs for consistent appearance.

Compatibility: Suitable for most vehicles with 12V DC electrical systems requiring 501/W5W bulbs. The 501 is one of the most common automotive bulb types. Check your vehicle handbook or existing bulb to confirm fitment before purchase.
