Last night I installed some Novsight 10,000 lumen (5,000 each) lights on my 2012 Super T. They were only $23.99 on Amazon so it was worth a shot at getting better illumination. I didn't think the stock lamps were very good. These are the ones I installed. They have the little cooling fans in them.
Here are the before and after pics of how they looked. These are the stock bulbs, low beam on the left, high on the right...
And the Novsight pair...
It doesn't look like it that much in the pictures, but the Novasights are definitely brighter. The most noticeable difference is that the new bulbs don't have the lumpy light projection that the stock set has which leaves dark patches on the road. The new lights are much more uniform, and they don't have the sharp cutoff of the stock low beams. That said, I was hoping for more of a "light up the night" effect from the Novasights based on their videos. Perhaps I was expecting too much and should just turn on the PIAAs for more light as needed. The install was a bit tricky as there isn't much room to get the wire clamp and connector out of the way and the new bulb situated and clamped in. I ended up going in from the front, taking out the headlight assembly to get at them. That was much easier. The new lights did require the extended caps. I bought a 3D printed pair off eBay. The first one went on fairly easily but I had trouble getting the tabs of the 2nd one to "catch" in the slots. Ended up breaking off two of the three tabs so that one is junk. I ordered a new set from Italy for unfortunately about three times the price. They are billed as being molded hard plastic rather than 3D printed so I'm hoping they will better stand up to my ham-handed treatment. In summary, I think the Novsights are a satisfactory upgrade for 24 bucks.
