Need a bit of help/advice, I have a 1993 (K reg) Discovery 200 tdi and the headlights are not that good so I want to know if I buy new ones do I go for the 200 tdi lights as a replacement or maybe buy a pair of 300 tdi headlight, and if I do go for the 300 tdi headlights is there much of a difference in brightness, what mods would I need to do to fit them and how hard is it to fit them.
