What would cause the low beam headlight not to work when all other lights work?


If you have standard halogen bulbs:

  1. Burned out light bulb; or
  2. Fried wires between the dashboard wiring harness and the headlight bulb connectors; or
  3. Fried headlight bulb connectors.
If you have HEI emitters:
  • Failed ballast.

One low beam head lights will not work, high beam works though


check for a damaged wire for the low beam. Also wouldn't hurt to check the ground wire as the high beam will try and ground through the low beam but not visa verse

I have a 2006 civic SI. DRL indicator is on, driver side low and high beam ok. Passenger side low beam ok but DRL and hi beam not working. Any help is appreciated.


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 :-(

I put in a new headlight bulb in the drivers side in but i dont have low beams but high beams work what is the problem?


Usually the low beam light of the bulb burns out first, so this new bulb is acting like it is defective. If the passenger side bulb is working for both low and high beams you could test this new bulb on that side to be sure. If it works OK on this side there may be a problem with the connector wiring on the driver side.

Both low beam headlamps quit working suddenly. High beams still working. Fuses look good, plus, low beam driver and low beam passenger are two separate fuses. Is there a hidden low-beam relay?


Headlamp relays are most always in the engine compartment in one of several power distribution boxes. It could be the dimmer switch, DRL module, or both bulbs. This happens because the lights are so bright, one low beam has burned out, and goes unnoticed until the other one burns out also.
Daytime Running Lamps (DRL) use the low beam but at a reduced power, which shortens their working life. Hope this helps.

1986 volvo headlights won't turn on


Most common problem is burned connectors at the relay that switches from high to low beams. I think that in '86, the relay was still inside the car above the driver's left foot. If not there, it is toward the front of the passenger compartment on the driver side, between the front inner fender and the battery. If it clicks when you move the dimmer switch, you can follow the click to find it. If the wires are good, the relay contacts may have failed.
On my '91, I lost the low beams because the headlight circuit in the bulb failure sensor had failed. The bulb failure sensor was an orange can-shaped device directly below the steering column under the dash. The headlight low beam wires were gray, as I recall. A new sensor was $150, so I cut the wires and bypassed it. I figured I could tell if I had a low beam burned out. I did not need a warning light for that. The bulb failure sensor still worked for the tail lights.
