HIGHBEAM RELAY (BRIGHT BOX)
This is my first try at this site so I hope it goes.
I hear you guys talking about the "Bright Box" and you are paying upwards of $150 for it :'(, I found one from jc whitney (made for chevy but it works, part # 81ZX1821P) for $19.99 and put one in each of my trucks and they work great. the only drawback is you have to splice into your headlight wires, I added an inline fuse to the power wire and have been running it for over a year and it works great ;D 8)

I've installed used relays to operate lots of different electrical devices on lots of vehicles. My current favorites are old Caddy A.C. Relays. I bet I've collected dozens of them over the years and used them for horns, clearance lights, etc. etc.
The headlight fix is next on my Relay to-do list.

When making modifications to a design, it is wise to ensure the change won't exceed the capability of any part. In this case I am concerned about the headlight switch. My manual warns that there is no spare current available on 3500 trucks with cab lights and dually fender clearance lights, and that 2500 trucks without cab lights have only 4 amps available.
Another advantage to the relay approach is that the added light will get all of the vehicle's voltage, where the diode method will reduce the power by .6 volts.
