What is this H1 to H4 conversion? Is it just replacing the low beam harness with a high beam one? Discuss...

. Since I have the real JDM stanley headlights. They came in H1 for my high beam and H4 for my low beam. My stock was 9006k and 9005k.
All I did was go to the local auto-shop. Bought four H4 Pig-lets.(You can use H4 ones on both). Then Cut my stock Pig-lets off and used butt-connectors to attach the wires and crimped them. Then wrapped the butt-connectors in electrical tape. I rocked it that way for like 5 months then decided to put some wireing covers over it as I did today!
Its really simple. I know you can buy conversion kits but I did it the cheapest and easiest way since my car was already apart when I found out what I had to do. Eventually im going to get a HID kit that will replace everything.
Hope that answered your question.
