I have the IPF housings with 30/40A relays, 12 gauge wiring and 55/60W Osram bulbs, but recently upgraded to 100/90W bulbs.
This setup works very well.... for me....
The rural roads in the PI are poorly illuminated...
So many 70 series owners in Australia have long since given up trying to make the headlights brighter. That is why everyone that does any sort of night driving has aux lights. I have stock headlights (globes globes and all) and powerful aux lights. I run the fyrlyt 250w and a slightly upgraded alternator, best setup for my application, as i don't like blue or white light. Poor and old pic but this is the idea. Lightbar never got used. Camera shows the light as way more blue than it is.
