SMARTBALLAST
Product Information
Product Information
Smart Ballast for use with LED brake lights in cars with Cruise Control. Tested in Porsche models 964, 993 and 996. Other models on request.

The Bergvill F/X LED Smart Ballast is a circuit that allows for problem-free use of LED brake bulbs in Porsche cars fitted with a Cruise Control unit.
LED bulbs use considerably less current than normal incandescent bulbs. The reduced current load on the brake light circuit is detected by the Cruise Control unit as a fault, and it will not allow engaging of cruise function.
The Smart Ballast simulates the normal incandescent bulb current load, but without wasting energy or the need for bulky or very hot ballast resistors.

The Smart Ballast is ONLY needed if you are using LEDs only as brake lights. (and no normal incandescent bulbs) This means LEDs in the normal rear/brake lights, and LEDs in the third brake light if fitted.

Please note the following:

• Only ONE Smart Ballast is needed per car
Cars without Cruise Control DO NOT NEED this circuit
• You DO NOT NEED this circuit if you have the normal incandescent third brake light
• This circuit will only work for solving issues using LED brake lights in Porsche cars. It will not work for solving any issues when using LED bulbs in turn signals or any other purpose.

Tested in Porsche models 928, 964, 993 and 996. Other models on request.

Single cable for additional brake light, Black
The Genuine Porsche Third Brake Light Wire is an original equipment electrical connection component designed for Porsche 911 (993) Coupé models equipped with the centre high-mounted stop lamp (Option Code: M602). This connecting wire, identified by its black connector, forms part of the third brake light wiring assembly, providing an electrical connection between the vehicle's brake light circuit and the centrally mounted rear stop lamp.

Fits:
Coupe models only, with M602 - Centre high-mounted stop lamp
Porsche 993 (911) Carrera 2 (1994 - 1998)

Diagram ref no 2

Manufactured to Porsche's original specifications, this genuine replacement wire provides precise fitment and reliable electrical connectivity, helping maintain the correct operation of the high-mounted brake light.

Ideal for replacing damaged, corroded or faulty original wiring during brake light repairs, electrical maintenance or classic Porsche restoration.

What Is This Part?
This is a single wiring lead within the third brake light electrical connection. It connects into the lamp circuit rather than forming a complete vehicle wiring harness. The additional brake light assembly uses separate electrical leads, so identifying the correct lead matters when repairing a damaged connection. This component is relevant when inspection shows that the individual wire or its terminal needs replacement.

What Does This Part Do?

  • Provides an electrical connection: Forms part of the circuit serving the additional brake light.
  • Links the lamp to its wiring: Provides the individual lead used at the brake light connection.
  • Allows a localised repair: Replaces the affected lead where the surrounding wiring remains serviceable.


Why Replace This Part?
Ageing insulation, broken strands or deterioration at a terminal can interrupt the electrical connection to the third brake light. Damage may also occur if wiring is pulled, trapped or disturbed during work around the lamp. Replace the lead if inspection confirms damage that prevents a sound connection.

A non-working or intermittent brake light does not by itself identify this wire as the cause. Check the lamp, electrical supply and associated connections before deciding which component needs renewal.


When to Replace This Part?

  • Damaged insulation: Cracking, cuts or chafing expose the conductor.
  • Broken wiring: The lead is severed, stretched or has damaged strands.
  • Deteriorated terminal: Corrosion or physical damage prevents a secure electrical connection.
  • Confirmed intermittent connection: Testing identifies a fault within this lead rather than elsewhere in the circuit.
  • Damage found during lamp work: Inspection during removal or refitting reveals that the lead cannot be reused.


Where Is This Part Fitted?
Location: At the electrical connection for the additional third brake light on the applicable Porsche 993 Coupe, as part of the lamp wiring.

About 3rd Brake Lights

Porsche Third Brake Lights | Safety, Visibility & Authentic Design

Third brake lights, also known as high-mounted stop lamps, are an essential safety feature in every Porsche. Positioned higher than the standard tail lights, they increase visibility to drivers behind you, especially under heavy braking or poor weather conditions. Over time, these lights can fade, crack, or fail — making timely replacement vital for maintaining safety and compliance.

At Design911, we supply premium-quality third brake lights and assemblies designed to deliver precise illumination, reliability, and a perfect fit. Our range includes LED upgrades, smoked lens options, and direct-fit replacements for classic and modern Porsche models. Each unit is built to meet performance standards for brightness, clarity, and durability, ensuring both style and safety on the road.

Whether you’re restoring an air-cooled 911 or upgrading a modern Cayman, our third brake lights combine safety, design precision, and genuine Porsche performance appeal.

What Do Third Brake Lights Do?

Third brake lights enhance safety and communication between vehicles by providing an additional, elevated signal when braking.

Core Functions:

  • Increase visibility during braking, especially at night or in fog.
  • Reduce the risk of rear-end collisions.
  • Provide redundancy if lower brake lights fail.
  • Enhance the visual balance and styling of the vehicle’s rear design.
  • Maintain compliance with road safety regulations.

In a Porsche, where design and performance meet precision engineering, third brake lights play a vital role in safety and aesthetics alike.

Why Do Third Brake Lights Fail or Degrade?

Even high-quality lighting components are exposed to heat, vibration, and environmental stress, leading to deterioration over time.

Common Causes of Failure Include:

  • Burnt-out bulbs or failed LEDs.
  • Cracked or faded lens covers from UV exposure.
  • Water ingress leading to condensation or corrosion.
  • Electrical connection faults or damaged wiring.
  • Vibration-related damage from performance driving.

When a third brake light becomes dim, cracked, or non-functional, it compromises both safety and the car’s visual integrity — and can even result in MOT or inspection failure.

Why Replace or Upgrade Your Porsche Third Brake Light?

Replacing or upgrading your Porsche’s third brake light restores full braking visibility and adds a refined finish to your rear styling. LED and smoked-lens options also enhance modernity and performance appeal.
