2000 Maxima Low-Beam not working - Bulb OK.

How did you test the bulb? A lot of modern vehicles use 'twin element' bulbs so you can still get a 'good' reading on a blown bulb if you only testing one element.. If you still have high beam but no low beam it is most likely the bulb or a short somewhere in the wiring.

Check the wiring on that light. Also check the bulb with a couple of wires to the battery, or swap the bulb left to right to make sure the new bulb is okay.

Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. High beam headlights don't work or low beams don't work. If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Check your manual to find your headlamp relay.

When either the high or low beam light is out in either side, DRL (daytime running lights) indicator will come on. When one bulb goes out, that's a clue the opposite bulb will burn out soon, so its best to replace both bulbs. If it was a fuse issue, both left and right side would be out. If driver side is OK but passenger side is not, then its a bulb issue. A 2006 Honda civic takes 9006 (HB4) low beam bulbs and 9005 (HB3) high beam bulbs. Cheapest is online from Walmart site-2-store. After procuring, wear latex, vinyl, or ANY gloves to keep your (corrosive) oil skin from coming in contact with headlight glass bulbs. Your skin oil will chemically react and cause shorter life span on glass bulbs. Instruction don't tell you this, so you handle with your hands, then need to replace bulbs 3 years later instead of 5 years (or more) in the future. With gloves on, pop the hood and look behind each headlight. Turn counter clockwise to unlock headlight bulb holders. Its a quarter to half turn to unlock bulb holder lock. Replace one bulb at a time so you don't confuse high beam from low beam. The wire has a tab you need to lift to pull out & disconnect wire connector. You might need a slim narrow-**** (NOT phillips) screwdriver to lift the tab; or use your house key. Snap the wire connector to the new bulb, then twist into headlight housing to secure bulb holders, then move on to the next bulb to repeat the procedure. Pict below, 9005 high beam is on the left, 9006 low beam is on the right. Handle by grasping the plastic base, not the glass bulbs. The raised potrusion on the bottom center is where the tab locks onto wire connector. Replace all 4 bulbs now, but in the future, its likely the low beam will wear out before the high beam. In the future, replace only the pair, not all 4. The factory installs inferior bulbs that go out sooner, hoping you'll take to dealership and they ******** you with higher parts-n-labor fees. As opposed to Walmart online site-2-store, it would cost you AT LEAST triple in parts & labor from dealership to replace all 4 headlight bulbs :-(

Is the filament inside the bulb broken?
If so, the low beam is burned out.

Try swapping with the left bulb (assuming it works ok) and see if the right side works correctly.

If so, replace the burned out bulb.

Thanks for choosing FixYa and welcome. These new lights have two types lin one bulb, one for the low beam and one for the high beam. Find the bulb that isn't lighting for the low beam and replace it with a new bulb. If it doesn't work, you need to check the wiring to that specific light. Since it is only one, the new bulb should work.

Dear,

dont buy any harness or module etc.
It is just because the bulb holder as burnt off............please get it changed will cost u very less

thanx

You probably have a bad plug or a broken wire on the low beam of the left side. I would replace the plug for the bulb and run a wire from the low beam on the right side or , locate and bypass the bad section of wire going to the current plug if the plug is still good.

Have a bad light bulb, replace should be ok.

could be the switch. did you do anything to the switch when you changedheadlamps? maybe you put the lamp in incorrectly also did the brights work on the lamp that was "burned out"?
