so get the uprated loom on here first?Well, I have to say in my case with those bulbs there has not been any problems with overheating or
damage to reflectors. I don't drive every night, but have done some long night drives (more than 3 hrs,
a mix of high /low).
I did add relays and heavier wiring because the circuits had quite a large voltage loss, and combined with
the high wattage bulbs made an enormous difference for the better, and at a reasonable cost.
If you do fit the bulbs it would be best to do the same (relays and wiring) because more wattage means
more load on switches, etc.
