Kubota GL40 sunshade options

[Mpking]

I'm looking at possibly buying a L3540 and was hoping someone could fill me in on the different sunshade options listed on the build my Kubota website. The sunshade option lists standard ($424), deluxe ($560), and deluxe with front work lights ($681). Whats the difference between the standard and deluxe and are the front work lights worth the extra $$$'s? Thanks!
