Connecting the world of classic Porsche
  • Headlight relay set for: Porsche 911/912 74-89 ISO version art.no: HEADLRELGISO

Specially designed for installation in the G model 911

H1 and H4 bulbs create a higher draw and together with the long wire length and a relatively small wire gauge this results in a lower voltage to the headlights.

This relay set protects your (expensive) headlight switch and gives full current to the lights !

Low and high beam have a separate relay and iso socket.

The iso sockets are positioned in the spare mounting holes from the front fuse-panel frame (please check if you have these spare holes available before ordering)

Wire colors are as original and each wire has the right length.

Detailed instructions for easy installation are included.

Max 100watt bulbs are recommended.

2 Bosch type relays included.


5 minute installation, and no special tools required !
