My daughter has a 2003 V6 5-speed Mustang and this is my first post on this forum. She would like brighter headlights, which seems to be a common issue. I have read several articles on use of relays and heavier wiring to reduce voltage drop to the headlights with resultant brighter lights. This makes sense if the power goes through the headlight switch and low/high beam switch. It looks like the 2003 does use relays for the headlight circuits.
Do these models still have voltage drop to the headlights? Would rewiring with heavy gauge wire (10-12g) and new relays (30-40A) make a significant improvement? If rewired to carry heavier current, can higher wattage halogn bulbs be used or will they be too hot for the headlight lens?
Thanks,
