Just curious as to any problems anyone may have encountered after making this modification.

I measured just over 10 volts at the headlight plugs before adding the relays and just over 14 after the install.Without a doubt yes...the lights are a lot brighter but will the higher volts kill the lights in short order or possibly even melt the original wires between the lights and relay down?

I have ran about 7' of 10gauge wire straight off the alternator output stud around the engine compartment to a fusible distribution block with 20amp fuses,then on to the 40amp relays and then to lights.I also have added extra grounds for everything to hopefully avoid any problems.

I'm wondering now if I can just be super impressed at the drastic difference in light output or paranoid that at any given moment both my headlights are going to go boom.
