LED Smart ballast. Porsche 964 / 993

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.
