Standard - There are two types of projectors, one with silver rings round the projector lense, one without. The N1's are more traditional dual lamp style and save a couple of hundred grams.
Some debate as to which are the least dim.
I have just brought some N1 lights, I had the projector type with the 50% brighter bulbs in, They were shocking!! So found some N1 lights, they have H4 bulbs with fog lamps in to. I can see the road now!!
I didnt think the N1s look as good but i dont care now i can the road. Also with N1s you can have high & low beam xenon bulbs, White day lights.:clap:
