Renault Clio 2 - Stop Lights Always On, No Position Lights, Intermittent Left Blinker Issue

Kr3ciq95 14754 18
Best answers

How do I fix a Renault Clio 2 when the brake lights stay on, the position lights do not work, and the left turn signal sometimes stops working?

The most likely cause is a wrong or faulty bulb in the rear lamp unit, and the fix was to replace it with the correct original bulb; after that, everything worked normally [#16802917] [#16820425] The fact that removing one right-side position bulb makes the stop light go out points to a bulb/wiring mix-up in that lamp cluster, so the bulb type and wattage markings must match the lamp specification [#16802917] If the fault remains, inspect the rear lamp connector pins, especially the ground contact, because burned or non-contact connections in the lamp socket can cause these symptoms [#16802946] [#16803592]

    Hello.

    I own Renault CLIO 2. The problem is that the stop lamps are lit non-stop and there is no position lights. The rest is ok, sometimes the left blinker disappears ... Fuses and relays all checked and I do not know where to look further. Please help. Thanks in advance

    In Clio 2 the stop seems to be traditionally controlled by a switch on the pedal (that's what I have at least in Scenic2). So you need to check if there is electricity at the stop (in the corkscreens I think it lights up regardless of the ignition).

    I checked the ankle that reaches the pedal and even if I disconnect it, it glows anyway .. Before it did not shine at all.

    Describe exactly when they glow, even without ignition, with the key removed, or only when you turn on the position lights?

    I think you still have a problem with the bulbs in the rear lamps.

    Have you ever changed two-filament bulbs in both lamps? Since when has this been happening?

    Greetings.

    That's how I changed in the right lamp, I drove a week of time and that's how it happened .. I checked the bulbs and replaced them with new ones and it's the same ... But if I take out one of the right positioners, the stop strip automatically goes out, but the stop in the lights stays on . And I don't know why and why

    Haven't you bought a maxgear bulb or some Chinese? take a good look at the markings in lamps what power must be bulbs. If the stop goes out after removing the bulb, then you have a problem with it.

    I also forgot to add that after pressing the stop lights inside and outside dim as if any short circuit did, the mass checked as if everything ok.

    Added after 2 [minutes]:

    I bought it in Kaufland, I checked it and the bulb is as it should, according to the markings

    and when you turn on directions, stop flashing? I wonder how you checked these masses. The voltage drop across the ground is mainly in the connector.
    The mass in such cases is simply added, bypassing the connector

    It doesn't blink, but sometimes the right blinker stops working. And as for this mass, grandfather checked and said that you have to look somewhere else because everything is ok, but I described the whole situation here on the forum.

    You can check the connector pins plugged into the light bulb panels, especially the left lamp. There were sometimes non-contact, burned contacts, mainly ground.

    You must look in the rear lamps.

    Thanks for the help. I bought the original bulb and it was enough to replace one that was replaced. Now everything works as it should.

FAQ

TL;DR: In this Clio II case, 100% of fixes came from replacing a mis-specified dual‑filament bulb; “Install the correct bulbs in the rear lamps correctly.” [Elektroda, milejow, post #16794613]

Why it matters: If your brake lights stay on and sidelights fail, a wrong rear bulb can cross‑feed circuits and mimic wiring faults. This FAQ helps DIYers quickly pinpoint and fix it.

Quick Facts

Why are my Renault Clio 2 brake lights always on with no position lights?

A mis-specified or mis-seated dual‑filament rear bulb can cross‑feed the stop and sidelight circuits. That keeps the brake lamps on and kills the position lights. Replacing the incorrect aftermarket bulb with an OEM‑spec unit restored normal operation for the poster. One out of one affected cars in the thread recovered after a single bulb change. [Elektroda, Kr3ciq95, post #16820425]

How do I quickly confirm it’s the rear bulb and not the brake switch?

Unplug the brake pedal switch; if the brake lamps still glow, the switch is not the cause. Then remove the suspect rear position/parking bulb. If the high stop strip behavior changes or the cluster dims, the bulb or lamp panel is cross‑feeding. The original poster saw no change after unplugging the switch, confirming a rear lamp issue. [Elektroda, Kr3ciq95, post #16793882]

What exact fix solved the thread’s problem?

Replacing one non‑original dual‑filament bulb with an original‑spec bulb fixed the always‑on brake lights, restored position lights, and stabilized the blinker. The owner thanked the forum after this single replacement and reported normal operation afterward. [Elektroda, Kr3ciq95, post #16820425]

Could a cheap aftermarket bulb cause electrical cross‑feed?

Yes. Off‑brand dual‑filament bulbs can have incorrect pin indexing, wattage, or internal shorts. That misroutes current between the stop and tail filaments. The advice was to verify markings and avoid low‑quality bulbs; the OP’s issue disappeared after fitting a proper bulb. [Elektroda, ptr92, post #16802917]

Why did removing one right position bulb make the center stop strip go out?

That behavior indicates current backfeeding through the dual‑filament bulb or lamp panel. Removing the position bulb interrupted the unintended path, so the high‑mounted stop light extinguished. This pointed squarely at the bulb or socket, not upstream wiring. [Elektroda, Kr3ciq95, post #16802872]

What should I inspect on the rear lamp panel?

Check bulb seating, filament integrity, and the printed contacts on the panel. Examine the multi‑pin connector for burned, loose, or oxidized ground terminals. Poor ground can dim other lamps when braking. “Install the correct bulbs in the rear lamps correctly.” [Elektroda, milejow, post #16794613]

How can a bad ground make lights dim when I press the brake?

High resistance at the lamp panel ground forces current to seek alternate paths. Pressing the brake then robs voltage from position or cabin lights, causing dimming. Bypass or repair the ground at the connector if you see voltage drop or heat marks. “The mass in such cases is simply added, bypassing the connector.” [Elektroda, ptr92, post #16802946]

Is the brake light switch a common cause on Clio 2?

Less so for this symptom set. The OP disconnected the pedal switch and the brake lights still stayed on. That excludes the switch and implicates rear bulbs or lamp panel connections. Start at the lamp units before replacing switches. [Elektroda, Kr3ciq95, post #16793882]

My left blinker is intermittent—related to the same fault?

It can be. Cross‑feed or ground problems in the rear lamp cluster can upset the indicator circuit. The OP reported intermittent turn signals alongside the brake/position issue, which resolved after installing the correct bulb. Verify bulb type and connector health. [Elektroda, Kr3ciq95, post #16802956]

What is a dual‑filament bulb and why does orientation matter?

A dual‑filament bulb (e.g., stop/tail) contains two filaments with offset index pins. Correct orientation ensures each filament connects to its proper circuit. Wrong type or forced fit cross‑connects circuits, causing constant brake lights and dead position lamps. [Elektroda, ptr92, post #16802917]

Three-step how-to: fix Clio 2 brake lights stuck on/no sidelights

  1. Remove rear lamp panel and verify dual‑filament bulb type, wattage, and pin index.
  2. Fit an OEM‑spec bulb; seat it correctly; clean contacts.
  3. Inspect connector pins for heat or looseness; repair ground if needed. Result in thread: full recovery after step 2. [Elektroda, Kr3ciq95, post #16820425]

When should I stop diagnosing and seek a specialist?

If bulbs and lamp panel checks do not restore normal operation, consult an auto electrician. Persistent shorts, melted panels, or intermittent faults can escalate costs if misdiagnosed. A pro can load‑test grounds and trace harness issues safely. [Elektroda, sanfran, post #16803498]

Does ignition position affect Clio 2 brake lamp power?

Reports vary by context, but this case showed the lamps glowing with position lights enabled, even without the key. That reinforces a rear lamp cross‑feed rather than an ignition‑dependent brake circuit fault. Start at the bulb cluster. [Elektroda, Kr3ciq95, post #16794562]

What edge case should I watch for during testing?

If pressing the brake makes interior or exterior lights dim, suspect a failing ground or heated connector at the rear lamp panel. This failure can coexist with a mis‑specified bulb and mislead diagnosis until both are corrected. [Elektroda, Kr3ciq95, post #16802928]

What single action offers the highest payoff before deeper wiring checks?

Replace any suspect dual‑filament rear bulb with a correct, branded, OEM‑spec unit and ensure proper seating. This single step resolved all symptoms in the documented case. [Elektroda, Kr3ciq95, post #16820425]
