I fitted a set of the new style LED indicators to my ('05) 12GS today. Even though you are supplied with a fitting kit, it still needs a bit of wiring work. I cut my leads to shorten them as you'd end up with too much wire to tuck away once finished otherwise. I also soldered and heat shrinked the new connections just to be on the safe side. Everything works perfectly and the difference in brightness/visability is very pleasing.
Cost wise, I got them for £110 sterling after some discount.
Were they really necessary ?
No, but it is coming up to Christmas, right ?
