Hella 128 + TTG running together

[lars1965]

Is it possible to run with Hella 128 under the bumper fogs together with TTG fogs together on same wire and foglight switch ? im unsure if 4 x 12 v bulb is pulling to much current through the wire


thanks

Wow! You must have some serious fog where you live.

More to the point, four 55 watt bulbs will pull 18⅓ amps at 12 volts (15.7 amps when your alternator takes the voltage to more like 14 volts). I checked a few sources that rate a 14 AWG wire (similar to the metric size in a 911) somewhere between 15 and 20 amps, so you'd be in an area of concern.

Your 50 year old switches are a bigger concern. They're harder to replace and that kind of current isn't good for the contacts.

I would urge you to add some relays and run hefty power wires from the battery to the relays.


Personally, I would run driving lights with the Hella 128s rather than four foglights but its your car.
