You possibly could have a wiring problem? I have a similar issue, about 3-4 weeks ago I picked up my 240 and the only beams are high, when i turn on the lights it says my brights are on, and then when I click the lever for the lights back it doesnt hold, and only turns off one of my lights. Yet I do have the kouki front end so maybe it was wired wrong. And my backlights have a short, and my reverse lights dont work but the bulbs are fine. My suggestion has been to take my car to Nissan, which I haven't had time to lately, but yea the only thing I know to check would be shorts, wiring, fuses, and bulbs. Sorry if that wasn't much help tho lol
