Two things happen to the '13~'18 headlights to cause night blindness without obvious hazing. One is easily fixed and the other requires replacement. You can access the bulb cavities through the wheel wells with the front of the vehicle lifted. Get or make a very small dentist mirror to inspect inside the lamps through the bulb holes. If you find peeled chrome on the reflectors, the lamps are done, replace them. Aftermarket TYC's are fine (and of course Nissan branded), but watch out for "off" brands, cheap chrome dies quickly. If the chrome looks good, then the problem is aluminum oxide accumulated on the inside of the focuser lens. Make a cleaning swab about 6" long from cotton balls and a stick of your choice, basically any sort of oversized Q-tip. Douse the end with alcohol and swab the inside of the lens. This problem occurs because the chrome isn't really chrome, it's basically electro-deposited tinfoil. Heat from the bulb gradually oxidizes it and the gaseous AlOx residue deposits on the cooler surface of the focuser, eventually reflecting a large amount of the light from the bulb back into the headlight. Several good swipes with alcohol will restore about 90% of the light.
