Description
3. rear brake light CITROEN C5 I and II Kombi
The part is tested, 5 diodes do not light up, the diodes light up on the jumper, the part is usable
Part description
This is a third (upper) brake light for Citroën C5 I and C5 II Kombi cars with product number 6350P6. Parts of this type are often searched for precisely by number, because the connector and the design of the light must fit.
Condition according to test: the light is functional and usable, but 5 diodes are not lit and diodes are lit on the jumper. If you need a fully continuous light strip without dropouts, consider this limitation.

Installation recommendations
Generally/typically for third brake light replacement (exact steps may vary depending on specific car design and mounting):
1) Before assembly
- Compare the old and new part: shape, dimensions, connector, mounting and product number 6350P6.
- Due to the condition of the part, verify that you are satisfied: 5 diodes are off and the light is on the jumper.
- Check for damaged connector pins and cracked light body.
2) Necessary tools and materials
- Basic set of screwdrivers / bits (according to the type of fastening)
- Plastic pry bar for removing upholstery/covers (to prevent damage)
- A clean cloth or a mild contact cleaner
3) Step-by-step assembly procedure
- Turn off the ignition and secure the vehicle against movement.
- For safe electrical work, disconnect the battery (typically the negative pole).
- Access the space for the third brake light (typically by removing the relevant inner cover/upholstery).
- Disconnect the electrical connector from the original light.
- Unfasten the light fastening (screws/clips according to design) and remove the part.
- Check the landing surface and surroundings – remove dirt so the light fits properly.
- If part of the gasket mount, check its condition and proper seating (typically helps prevent leaks).
- Place the new light in the hole and fix it in the original way.
- Connect the connector and make sure it snaps in properly.
- Reinstall any covers/upholstery that were removed.
- Connect the battery.
-
4) Post-assembly checks and functional test verification
- Pull on the brake and check the third brake light.
- Account for the fact that according to the test 5 diodes do not light and the diodes may light on a jumper.
- Check that the light is firmly held and nothing vibrates.
5) The most common assembly mistakes + how to avoid them
- Not clicked connector → after connecting, gently pull the connector and verify the locking.
- Damage to upholstery/covers → use a plastic pry bar, do not pull the edges with force.
- Ignoring LED status → check the light briefly before final assembly so you don’t have to disassemble again.
- Aging of LEDs and gradual loss of luminosity of individual diodes.
- Moisture/leakage into the light area (damaged seal or leakage in the vicinity).
- Oxidation of contacts and transition resistances in the connector.
- Vibration and mechanical stress (loose attachment, cracks in the body of the part).
- Interference with the electrical installation (improper wiring, damaged wires).
