S Type Headlamp upgrade


Recommended Posts

Hi guys

Does anyone know if the headlamp wiring on an s type is capable of supporting higher wattage halogen bulbs?

I've used led bulbs which are great but not mot compliant and HID bulbs are not worth all the conversion work although I do have two projector lens headlights ready to fit or sale.

I'm tempted to use 80 or even 100watt halogen bulbs instead of the standard 55watt bulbs but I what stage do I upgrade the wiring to cater for the higher outputs?

I would not chance it because all the loads goes through the body module which switches the lights on and off

if your handy with car wiring, you could install 2 relays, that have a separate 12v supply, then you can install any wattage you want
