So the headlight circuit is fused with a 15A fuse. The headlights on high beam draw 65 Watts, which at 12 volts is only 5.4A. What if I added more lights to this circuit? Any reason to think that could cause an issue? The relays the headlight power runs through (starter relay and headlight relay) are both rated for much more than 15A.....   So, would be crazy to put more load on this circuit? Could doing that impact anything else? Could the Regulator/Rectifier be damaged?   Electrical wizard
