I carry the same kit on my electronic ignition cars. Have yet to use them except for testing.
in over thirty years of driving these cars, I had only one ballast ever go bad. Still carry em in the trunk…… just in case.
I agree. The day I dont have it is when it'll fail. As long as I keep it in the trunk it'll probably never break lol.
Got my conversion housings in for the H4 bulbs, glass, seem really nice, and look original. I bought a relay harness, and beefed it up a bit, some of the ground wires were a little chinsy looking. Also have LED brake and marker lights. Should take some of the electrical load off. If I don't burn the car down I'll take some pictures of the new set up this week.
