Bulb Socket Holder with Wire 1156 BA15S P21W

The 1156 BA15S Bulb Socket Holder is a pre-wired single-contact bayonet lamp base connector designed for use with P21W, 1156, and compatible single-filament automotive bulbs. Fitted with two wire leads for straightforward solder or splice installation into existing vehicle wiring, this socket adapter is the go-to solution for repairing damaged lamp assemblies, building custom lighting setups, or retrofitting standard bulb holders for LED upgrades in cars, motorcycles, boats, and recreational vehicles.

The socket features a heat-resistant body, a non-rusting steel spring contact, and a rubber seal for moisture resistance — ensuring reliable performance in the demanding under-body and exterior lighting environments typical of automotive use. The parallel (even-height) bayonet pins accept any BA15S single-contact bulb with a 15mm diameter base. Compatible with both 6V and 12V systems, it works equally well with incandescent and LED bulb types. Suitable for reversing lights, brake lights, indicator lights, tail lights, and fog lights across a wide range of vehicle makes and models. Cross-references include the 382, 7506, 1141, 1073, 93, and 97 bulb socket types.
