headlights

Well I thank you for all of your advice I just have one last question for dan. Im getting ready to redo the wiring on my 74 duster, what is a good company to go with for a complete new wiring harness for the whole car. I want to replace everything and update. None of my lights are putting out any light output at all. Everything works properly except for the horn going to fix that today. But everything is so dim its just not safe. Now I know that I can ad grounds to all the lights and they will be brighter but I have my doubts that they will be good enough to be safe and legal because right now they are not, which is why I want to rewire the whole car. I know painless but they are ridiculously expensive. Any others brand or manufacturers you know of?
thanks travis
