Well the Nissan is better for beam, both my Chevy and the Nissan's beam reach the same distance....but the Nissan's beam is more solid on the ground...mine has some uneven spots due to it being in a halogen housing.
The Maxima has some great cutoff as well.....we were driving through the back woods of Louisiana, so I definantly put it through the test. I'm thinking they cutoff by making the bottom part of the reflector square instead of curved. Here's a pic:
The one on the left is what most reflectors look like from the side, the one on the right is what the Maxima's looks like.
Now I'm just guessing that's for cutoff, if anyone has noticed this and knows why it's like that, please let me know.
