Base for Lamp 2 pole (made in India)
DUAL CIRCUIT CONNECTOR: Lamp Base 2-Pole (BA15d/BAY15d) – Essential Socket Component.
This item refers to the socket or connector base designed to hold and power a dual-filament signal bulb (like the P21/5W or 1157 type), commonly used for Brake/Tail Lights or Front Position/Turn Signals in older vehicles. This connector transfers power to two separate filaments (two circuits) inside the bulb from the single socket.
Since the product description does not provide a specific part number, manufacturer name (other than the country of origin), or material type, the details below are based on the globally recognized standards for this two-pole bayonet connector, which is a common spare part in markets where wiring/socket repair is routine.
KEY SPECIFICATIONS: BA15d / BAY15d Standard
The "2 pole" designation indicates a dual-circuit connection, typically used for simultaneous running light and brake/signal light functions.
| Specification | Detail | Direct Benefit to the Egyptian Driver |
| Circuit Type | 2-Pole / Dual Circuit | Dual Functionality. Enables the bulb to serve two functions (e.g., 5W parking light and 21W brake light). |
| Common Base Standard | BAY15d (Offset Pins) or BA15d (Parallel Pins) | Fitment Critical. This base is identifiable by its two contacts on the bottom and two locking pins on the side. BAY15d (offset pins) is most common for P21/5W bulbs. |
| Voltage | 12 Volt | Standard Automotive. Designed for use with all passenger car and light truck electrical systems. |
| Material (Typical) | High-Heat Plastic / Ceramic / Metal | Thermal Resistance. Must withstand the heat generated by the 21W filament and resist deterioration common in the housing. |
| Application | Brake Lights, Tail Lights, Turn Signals | Safety Repair. Used to repair damaged, corroded, or melted bulb sockets, preventing further electrical faults and bulb failure. |
| Origin | Made in India | Cost-Effective Sourcing. Provides a readily available, value-focused replacement component. |
WHY THIS CONNECTOR IS A MUST-BUY
The connector (or base) is often the root cause of electrical faults, including intermittent operation and high-resistance heat buildup, due to corrosion or moisture ingress.
Fixes Electrical Corrosion: If your socket is corroded (the main cause of flickering or non-working lights), replacing the base is the only reliable way to restore a clean, low-resistance electrical connection.
Prevents Heat Damage: Worn sockets cause high resistance, which melts the plastic housing. A new, high-quality replacement base stops this destructive cycle, protecting the entire light assembly.
Guaranteed Bulb Function: Ensures the critical dual functions (Brake/Tail) operate correctly and reliably, which is paramount for road safety.
RESTORE YOUR LIGHTING SOCKETS.
Crucial Check: Before purchasing, identify the exact model base of your old bulb/socket to ensure correct fitting, as BA15d (P21W) and BAY15d (P21/5W) look similar but are NOT interchangeable.
