I know that the California headlights could be better. One upgrade is changing the headlight bulbs. Easily done.
However the wiring from the headlight switch to the lights themselves does cause a not insignificant voltage drop which can be countered by the use of relays to switch power directly from the battery to the headlight and using the existing wiring to just switch the relays themselves. Using thicker wiring from battery to relay to headlight minimises the voltage drop and hence brighter lights.
I've done this on my Defender, but it does not have a Canbus lights warning system. I know you cannot just change road bulbs to LED without a resistance in circuit otherwise you get a bulb fault, But what about the use of relays? is there sufficient resistance to prevent a bulb fault showing?
