BA15S Auto Bulb Holder Cap Screw Terminal

Add or replace a turn signal, brake, or tail light socket with this BA15S Auto Bulb Holder Cap, a metal socket base built to accept standard 1156-style single-contact bayonet bulbs. Its parallel bayonet slots match the BA15S base found on common automotive bulbs, giving you a durable metal housing to mount and wire into your own lighting setup.

This holder uses a single brass screw terminal inside the cap, letting you connect your own wire gauge and length directly with a small screwdriver, no soldering required. This makes it especially useful for custom wiring jobs, repairs where the original wire is too short or damaged, or builds where you need a specific wire color or length that a pre-wired socket wouldn’t offer. The nickel-plated metal shell resists corrosion and holds up well to the heat cycling that comes with regular bulb use, while the open rear allows easy access for wiring and mounting. As a single-contact socket, the metal body itself serves as the ground return path once mounted to a chassis or grounded bracket.

This bulb holder cap is a practical part for hobbyists and DIY installers building custom lighting harnesses, repairing damaged sockets, or wiring aftermarket LED bulbs into cars, trucks, motorcycles, boats, and other vehicles using the BA15S/1156 bulb standard. Please note this is the socket cap only; the bulb and wire are sold separately.
