Hi Guys!

 

Strange one here, yesterday leaving work I noticed my main headlights were not working, beams both work (both pushing the stalk toward and away from myself) and sidelights work, only the main headlights do not.

 

I tried changing both bulbs however the same thing occurred. I also changed the fuses, however the headlight are still not coming on! I changed fuses 36 (Mainbeam), 58 and 57 (Right low beam and Left low beam) all 15 amp.

 

The headlight light on the dash does appear when the headlights are set to on so I'm guessing the actual switch to turn them on is out of the question and not the prob.

 

Any help is appreciated, thank you!

 

 

 

Dipped beam bulbs blown on both sides.

 

How many headlight bulbs do you have, and did you touch them when fitting them?

 

Thanks AG Falco

Hi Falco

 

Thanks for the reply! Are the dipped beam bulbs different to the headlight bulbs or are they the same bulb? 

 

I got 2 new bulbs, I thought to replace both sides. Did not touch bulbs when fitting

Dipped beam and high beam are the same bulbs its not 2 like on the vrs

Some bulbs are twin filament so one can blow, whilst the other still functions. Others have a single filament, with an electric motor that operates a flap, that blocks off the top half of the beam. This should make it obvious if the bulb is either working or not. Also, make sure you fitted them correctly. It is quite easy to make an error.

Hi Mrgf!

 

The bulbs are twin filament, bulbs have been fitted correctly as full beams are working on both sides.

 

If you only have two headlight bulbs ( H4 with three connectors on the back ) that have two filaments in them then try this.

Take the bulb out and look at each filament to make sure that they have not blown.

The filament should look clean and one is above the other 

 

Then try them with a piece of wire and the car battery to see if both filaments work out of the car.

If both filaments work out of the car then it is a car problem.

If you look at bulb connections with one each side and the third at the top then at:-

9.00 is the common earth,  12.00 is for dipped and  3.00 is for main beam.

 

 

If you turn the ignition on and just the dipped beam switch then check the headlight wire connectors on the car for voltage.

Of the three connections one is for dipped/green, one is for main/blue and the third is the common earth.

These will correspond with the bulb connections.

 

Do the same but with the main beam switched on.

If there is power on main but not dipped then look at the light switch for your problem.

That could be your issue if you’ve fitted twin filament bulbs when it should only be single. 

Miral, do you have projector headlights at all? They will look like they have a spotlight inside from the front of the car. 

If so, AMD87 might have a valid point! Some cars have H4 bulbs, whilst others have H7's

I have very similar problem on my octavia I have just purchased, the passenger side light not working, I changed the bulb but it was fine, seems no power going to this bulb, any ideas if could be the switch inside the car?  it was being intermittent off and on, but only from switching on ignition some times the light warning would come on sometimes not?

when I switched the bulb it worked , I put the light back in car then switched on ignition and not working again!   where can I look for this problem, 

the wiring around bulb looked fine, I test meter the bulb fitting and was not getting 12v,, only 0.30. so seems no power coming through, 

any ideas? other sidelight is fine 

Swap the bulbs from side to side to prove that it is not the bulb.

Sometimes the wire connector that fits on to the back of the bulb is loose.

 

It wants to be a firm push fit.

Wire broken where it joins the block connector?

Yeh I already put completely new bulb in , the bulb houseing look fine and wire also look fine , I’m stuck as to where the problem lyes 

Don't assume that the new bulb works, have you tried swapping them from side to side?

 

Thanks AG Falco

Typo no 's

The new bulb worked , I switch car off then replace light back onto car , then close bonnet , then I switch car and lights on and it no good again ,

i take light out again and repeat process , the bulb not blown , the bulb I removed did also not look blown 

Have you tried swapping them from side to side?

Also with the bulbs in the car try wriggling the wire connector block when fitted to the bulb in the car.

Also check for voltage at the back of the wire connector block when fitted to the bulb in the car.

 

Thanks AG Falco

I scanned car with vcds and get this ,

seems fault in circuit ,, anybidea where to common place for falure would be to start looking ? 

Edited 8 December, 20187 yr by alesypalsy

The fault lists 'Parking Light Left Front' not headlamp bulb?

Do your parking lights work?

Bad earth?

 

Thanks AG Falco

Just like to update to my problem , it seems the bulbs had both blown and I put a LED bulb in and it’s all good now , 

thanks for the advice 

It was my side light, looking at the car from front it was bulb top right corner above the indicator bulb , small little bulb 

Please correct if wrong but for the facelift Fabia Mk2 ( when models badged S, SE & Elegance rather than Level 1, 2, 3 ) I am aware of 3 headlight configurations.

 

The S model had basic non-projector units and a single bulb with 2 filaments for dipped and main beam.

 

The earlier SE and Elegance had projector units with two separate single filament bulbs for dipped beam & main beam. This is the configuration I have. The dipped bulbs are H7, I have never changed a main beam one.

 

The later SE and Elegance had projector units with one single bulb filament bulb for dipped beam & main beam. The dipped beam was set by a moving flap.

 

I don't know about the VRS at all.

And just to confuse things further the OP Miral has a Fabia II with a headlight out,

then alesypasey comes in with an Octavia ( but their showing as having a Fabia III ) with a parking light problem.

 

I hope Miral has sorted their headlight problem.

 

Thanks AG Falco

Aleseypalsy also later stated he/she had an LED bulb. These CAN show up a fault on some models whilst being fine on others. Additionally, many LED bulbs are pole sensitive. Pop them in one way round, they work, the other and they won't. This is not a fault, just design. If you fit any LED to any vehicle and at first, it won't light up, pop it out, turn it the other way round and try again. Also, they drain such a low voltage that many cars think there is a blown bulb, so tell the driver of this with a warning light or code. The other issue is on signals. As the bulb draws such a low amount of power, the signals can flash twice as fast as normal, which again, is the car telling the driver there is a blown bulb! In this situation, a resistor may well be needed.
