BAY15D Auto Bulb Holder Cap Screw Terminal

Add or replace a turn signal, brake, or tail light socket with this BAY15D Auto Bulb Holder Cap, a metal socket base built to accept standard 1157-style dual-contact bayonet bulbs. Its offset bayonet slots match the BAY15D base found on common automotive bulbs, giving you a durable metal housing to mount and wire into your own lighting setup.

Unlike pre-wired sockets, this holder uses two brass screw terminals 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.

This bulb holder cap is a practical part for hobbyists and DIY installers building custom lighting harnesses, repairing damaged sockets, or wiring aftermarket LED clusters into cars, trucks, motorcycles, boats, and other vehicles using the BAY15D/1157 bulb standard. Please note this is the socket cap only; the bulb and wire are sold separately.
