OK,
I bought these lights from Octane Lighting on ebay:
http://www.ebay.com/itm/4x6-WHITE-LED-H ... 35c8dec573I also bought the wiring kit they sold. I could have made my own harness, but this looked pretty turnkey:

The lights are a straight swap for your current lights, except you have to cut your headlight buckets like I did as the back end of the lights are bigger to accomodate the projector lamps. I unplugged my old lights, removed them, took out my original buckets, put in my modified buckets, put in the new lamps, hooked the new wire harness to the lamps, plugged in the new wire harness to the far left plug of the old wire harness, mounted the two relays, hooked the red power wire on the new harness to my power lug by the brake booster. Hooked the grounds up at the normal spot between the headlights. I had a little trouble at first as the brights would be on when they weren't supposed to, but Octane has great customer service and all it took was a couple of emails and phone calls to determine that one of the wires was in the harness wrong for my application. I just switched the white and black wires on the input side of the new harness and I was good to go.
For the LED's, I got some red 18 gauge wire and black 18 gauge wire, bought some "t" style connectors and ran the wires with connectors from the right headlights over to the left headlights and in the case of the black wire, just grounded it with the headlight grounds (The LED's have two red and two black wires per headlight coming out, so it's kind of a pain to wire up, but if I can do it, anyone can). Then for the red wire I just ran it from the right lights to the left lights then up the inside of the left fender to the firewall. This is where it got tough. I knew I needed to get to the fuse box to hook into a power lug that was switched with the ignition, but the firewall on these cars is tight (my '68 by comparison you can stand back a couple of feet from the car, throw a wire at the firewall and you have a fairly good chance of it going through). I had to run a stiff wire through the grommet that the speedo cable goes through (literally through the grommet, there was no way to run it through the hole the speedo cable goes through, it was too tight. I used a leather punch to go through the grommet, then put the stiff wire through the path the punch made (which had already closed up by the time I pulled the punch out)) then duct taped the red wire to the stiff wire and pulled it through into the driver compartment. From there I connected the wire to the fuse box. Now when I start the car the LED's light up.
I don't know how long these will last. Hopefully a long time. I was fairly impressed with the product and the customer service, so I ordered a set of halo lights for my '68. (

If you have any questions on any more of this please put them here and I will try to answer them. When I get a chance I will shoot a picture or two of what things look like on the back side of the lights and under the hood.
