I have just learned that you do not need a front head light to get a spark but it is important for youre taillight to work. I just picked my 78 green (goblin) Express up from a garage sell and I can already imagine that we will have several years of fun togeather. Hey just keep on it and good luck. I dont really know much yet about the electrical but I do know that just about any key will work for the iginition. Also I just learned that you can find an alternative to the sealed beam headlight. You can find a light that is actually even brighter then the sealed beam and instead of spending $30.00 replacing the whole sealed beam when it is allot cheaper and also a bit easier to replace!
