Siteunseen, it's my understanding that Dave's harness(s) are better. I have both of them and am very happy. You are correct, it does pull power from the battery instead of the switch.

Mark, thanks for the info. Not sure what I'm going to use yet. I like the idea of being able to reach in and replace the bulb instead of having to replace the whole headlight.

I need to research this some more.

78 Z Car, very nice job, I'm a little over 2 years in my 75 and on the home stretch. I was going to sell her this Spring but have changed my mind, there are a few things left to do, just got some new 16" rims and tires, didn't really like my rims.
