LED Smart Ballast

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.

We get these common questions:

  • Do I need the Smart Ballast if my car has the Cruise Control system, and a LED third brake light and LED rear/brake light bulbs? Answer: Yes
  • Do I need the Smart Ballast if my car has the Cruise Control system, no third brake light and I install LED rear/brake light bulbs? Answer: Yes
  • Do I need the Smart Ballast if my does not have the Cruise Control system? Answer: No
  • Do I need the Smart Ballast if I still use the original incandescent bulb third brake light? Answer: No
  • Do I need the Smart Ballast if I still use the original rear/brake incandescent bulbs? Answer: No
  • Do I need two Smart Ballasts, one for each rear light? Answer: No
  • Do I need two Smart Ballasts if I use LED turn signal bulbs?  Answer: No


The Smart Ballast is only needed if the car has cruise control and when you are using LED bulbs only as brake lights, and no normal incandescent bulbs. This means LED bulbs in the normal rear/brake lights, and third brake light, or LED bulbs in the normal rear/brake lights, and no third brake light is 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

The Smart Ballast is only tested in conjunction with our 1157 red LED brake light bulbs. Other makes of LED bulbs may introduce a different total load resistance on the brake light circuit. This circuit will only work for solving issues using LED brake lights in Porsche cars fitted with a cruise control. It will not work for solving any issues when using LED bulbs in turn signals or any other purpose.

The Smart Ballast is tested in Porsche models 928, 964, 993 and 996. It is also used by our customers with great success in other types of vehicles such as BMW, Mazda and Victory motorcycles. However, we do not guarantee or can help in other use than the above mentioned main purpose for the device.
