if it is a h4 headlight it could be that the wires are mixed up, it could be that while on high beam they are fine but when on low beam that the low beam part of the bulb has blown and tour left headlight is just being lit by a sidelight bulb, best off just to get two new headlight bulbs fitted first as it could just be a blown bulb and the cheapest fix is the best!

Could be a defective headlight relay, Located in the fuse block in engine compartment,

the low beam element has burned out in the light bulb itself - buy and install a new bulb,, this will fix your problem. ( your local auto parts store will carry the replacement bulb ).

12 METERS THE LOW BEEN SHOULD BE THE HIGHT OF A BUMPER , CONCENTRATED LIGHT SHOULD BE STRAIGHT ON THE LEFT SIDE AND THE RIGHT SIDE A LITTLE BIT TURNING TO THE RIGHT.

Bad lamps? bad connection to lamp? I know already checked :( right?

You have a bad ground on the left low beam. Using a test light connected to ground see what wire is positive with low beams on. Using a piece of electrical wire connect one end to ground and with the headlight connector connected to the headlight and headlights on stick the other end into back of the connector at the ground wire. If the light gets brighter, you can cut the original ground wire to the connector ( 2-3 inches from headlight connector) and run a new wire from ground and connect it to the wire at the connector. Hope this is helpful.

If I remember correctly nissan uses a L&R high and low beam fuses,might want to double check them,but if you need any diagrams just ask have a good day DB

You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.

I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp

the headlight fuses are always the first four going from left to righ on a volkswagen 1 for left lowbeam rigth low beam left high beam right high beam.
