Instead of buying 'NightEye', I chose the trusted TVS brand with a year of 'actual warranty'. Apart from that, there're a lot of fake NightEyes around (although I believe NightEye itself is fake, cheap, Chinese stuff.).

Compared to NightEye, this's almost twice more expensive and has significantly less brightness. It takes up 30W, compared to 36W of NightEye and of course has significantly less brightness (as per the specs, if NightEye's specs are real).

Now coming to the beam, the low beam was never a problem with LEDs, but the high beam's focus is also good, although not as good as halogens, but the additional brightness (2x) compensates for that. The high beam feels more like a torch.

Color of the beam is 100% white, but using the low beam, there's some refraction which'll give a mild rainbow effect on the borders of light as thrown by the low beam.

Overall, a good option for the RC especially if you're planning to reduce power consumption (follow AHO).
Price: 3500. Very easy to install; the drivers are integrated inside the bulb case, so you wont have a drip bottle hanging around. Just take a box of H9/H11 bulbs which'll have 2 identical headlights.
