I got the cibie z-beam headlights I had in my 85 ram 50 royal I had bought when the truck was new - putting 80/100 in the outer lights and 100w zenons in the highs, and I am building a high power harness for the lights with relays wired to the battery for full power to the lights. When I ran this setup with the stock wiring on high beams I would light up signs on the interstate 2 miles away bright as daylight wonder how far they will throw with a full 12 volts to the bulbs - through the harness is about 9-10 volts after the losses in the harness. These are going into the 86 project truck btw, as Geronimo has a similar setup wiring wise, but the headlights are toucan projectors - no where as good as the cibie z-beam headlights.
