<<<In regard to installing optional higher wattage lamps, isn't the purpose of the relay to remove the headlight current from the headlight switch?>>> Headlamp amperage draw would be a better analogy. <<< How would the installation of higher wattage bulbs affect the headlight switch?>> Without the relays, you'd for sure melt the headlamp switch ,and the dimmer switch.
<<Is the stock wiring harness sized for 20-amps of current draw?>> Sure. Each operation of the lamp circuit is fused individully, so if there was an overload the fuse would fry before the wire.
<< Can you safely install higher amperage fuses in the headlight circuits without melting down the wiring, fuse block or bulb connector?>> Yes.
<< It was my understanding that circuits are fused to protect the wiring, not to protect the device.>> Both the wiring, switches, as well as the accessory. |
