i have virtually the same diagram in my manual..the bottom is flstc,flstf...the middle is fxst,fxstb..the top is fxstd,flsts,fxsts .
that is an excellent idea, replacing the sealed beam with a bulbholder. hadnt thought of it. been in touch with trucklite, confirmed that their bulb will replace mine which is a type H6024, waiting on pricing info. thanks for the idea..
