I had a guy come to me with a loose head light. I couldn't see the crack at the base till I took it apart, and found the whole bottom was busted out of it. I JB welded it on the inside, that was 5 years ago, and it's still holding, and the chrome hasn't peeled.
I'm sure the Kaptin can fix you up with a new light if that one is beyond repair.
I like Adjure but I bought the bucket with it. It is very easy to remove the headlight to get to the bulb. Also, it is a much cleaner light and causes people to ask if it is HID.
I was a little concerned about heat issues if I went with a H4. I found a H4467 sealed beam upgrade from the 4467. Suppose to be just a little more light and a little more white. Gotta be better than the flashlight beam I was getting off the OEM.
