Purpose and function of the component

The offered bulb holder is dedicated to the rear right tail light in the first-generation Toyota Aygo model. Its task is to keep the bulbs in the correct position and ensure a stable electrical contact with the vehicle's wiring. This ensures that the position and brake light system operates predictably and that light signals are clearly visible to other road users. The component belongs to the Rear lights and brake lights group, which means it is responsible for one of the key safety areas – signaling braking and vehicle presence. A properly selected and functional bulb holder reduces the risk of circuit interruptions, flickering lights, or overheating contacts.

Construction and installation fitment

The Toyota Aygo B1 Rear Tail Light Lamp Bulb Socket Holder Right O/S has been designed as an OEM part, maintaining factory geometry and mounting methods. Properly shaped bulb sockets and the connector for the electrical harness allow for installation without modifying the wiring, which is particularly important for repairs performed according to the manufacturer's guidelines. The placement on the vehicle, specified as the rear, right side, ensures precise fitment for the specific lamp. Such a solution minimizes the risk of errors when selecting parts and facilitates service work, especially in workshop conditions where repeatability and predictability of installation are crucial.

Benefits of using an original bulb holder

Using an original bulb holder in the tail light provides a number of practical benefits:

• Factory fitment – compatibility with the design of the Toyota Aygo B1 lamp and electrical harness.
• Stable bulb mounting – reduction of play that can lead to power interruptions.
• Proper operation of position and brake lights – clear signaling for drivers behind you.
• Reduced risk of contact overheating – properly designed contact areas.
• Easier diagnostics – maintaining the original architecture of the lighting system. For the user, this means more predictable operation, and for the workshop – faster installation and a lower risk of complaints related to unstable lighting performance.

Component condition and service application

The offered bulb holder is a used part, which in practice allows for an economical repair of the lighting system while maintaining the original manufacturer's specifications. This type of part is particularly useful in situations where there has been mechanical damage to the lamp, melting of the bulb sockets, or corrosion of the contacts, and it is necessary to restore full functionality without interfering with the electrical harness. Replacing the bulb holder is a typical service operation performed during post-accident repairs, after lamp flooding, or during long-term operation in harsh conditions. Using an original component helps maintain the integrity of the installation and facilitates any future diagnostic work.
