Purpose and vehicle placement

The presented holder is a component from the Rear lights and brake lights group, mounted in the rear tail light of the Citroën C4 Grand Picasso. The design is intended for installation on both the left and right sides, which facilitates part selection during lighting system repairs. Its placement in the rear body zone allows for the support of key vehicle signaling functions, such as position lights, brake lights, or turn signals – depending on the specific lamp configuration.

Construction and technical function of the holder

The rear tail light bulb holder in the Citroën C4 Grand Picasso serves as a carrier for bulbs and a connection point with the vehicle's electrical system. The applied mounting geometry allows for stable seating in the lamp housing, and properly shaped contacts ensure even contact with the bulb terminals. This reduces the risk of circuit interruption, light flickering, or local contact overheating. The arrangement of the bulb holders is adapted to the optical layout of the rear lamp, which allows for maintaining the correct focal length and light direction. In practice, this translates into clear signaling for other road users and compliance with the vehicle's factory lighting parameters.

Benefits of using an original holder

Using an original bulb holder in the Citroën C4 Grand Picasso allows for maintaining the consistency of the electrical system and avoiding problems typical of aftermarket replacements with imprecise fitment. The most important advantages include:

• secure mounting in the rear lamp housing, reducing play and vibration of the component,
• stable electrical contact, promoting even light operation,
• preservation of the factory bulb layout in the lamp,
• easier diagnostics of potential lighting faults due to compliance with the original design. For the user, this means more predictable operation of the lighting system and a lower risk of needing further intervention in the rear lamp after the repair is completed.

Product characteristics and service application

The offered holder comes from the Citroën brand parts group and is a pre-owned component, which in practice represents a favorable compromise between repair costs and maintaining the original design. This type of component is suitable both for replacing a damaged holder after an electrical failure and for post-collision repairs when the rear lighting needs to be rebuilt. In service applications, the Citroën C4 Grand Picasso rear tail light bulb holder allows for:

• restoring full functionality of the rear lights after damage to the factory element,
• reducing problems with intermittently failing brake or position lights,
• maintaining compatibility with the vehicle's existing electrical harness.
