No Power To Headlight? :/
- Thread starter sfmk2.
- Start date
Can you elaborate at all fella?
On the back of the dipped bulb there is a little block connector that slides onto the 2 prongs on the bulb. Thats's on properly...
That was the bit I was referring to. Can you track it back to it's power source at all? Hopefully it's something like a dodgy connector.
Might be worth checking the fuse although I think the whole headlight wouldn't be working if it was that.
Not without taking the headlight out
By the looka of it the same fuse powers both full headlight units and more too. Had the fuse out and its fine.
Looks like a trip to the stealer in the morning... Just what I needed
Thanks though both of you! Appreciate your help.
My other bulbs in that cluster all work, and my passenger side dipped still works. It's just that one
I did a quick google search and found this, not sure if it is the leon or not as i havent seen the fuse box haha, but here it is anyway,

I don't think it's the Leon, but I'll certainly go out to the car & check it again. Thanks mate.
Really scratching my head over this one. It's boggling me big time
If you thought you were confused before, this will send you loopy. Depending on what year the car is, the fuses are in different locations and not fully clear what they control.
Up to May 06
Fuse 5, 5A, Left and Right Headlights

Fuse 24, 20A, J519
Fuse 28, 30A, J519 (with Autolock)
Fuse 34, 25A, J519 (without Autolock)
These are taken from ElsaWin. My car is May 2010 but the Owners Manual shows the headlights as Fuse 2 but it was printed in April 2009. Apart from Xenons, it does not appear that the headlights have seperate fuses.
All these are in the fusebox at the end of the dashboard. It appears that on RHD models, the fuses number from RIGHT to LEFT.
Thanks for that, much appreciated. My handbook shows Fuse 2 is for my light control unit but that's intact.
I've just run round to my local stealer and one of the chaps had a good look.
The fuses are all fine, so I need to book it in to be checked. He couldn't understand why one HL worked, but the other didn't. Especially as they're both powered directly from the light control unit.
I think it could be a blown relay, but that's pretty much foreign to me, so we will let them sort it out!
Try this first....
I had the same problem, I fitted HIDs and the ballast went a bit funny and the light went off.
Replace with standard bulb to get me going until i ordered a replacement HID ballast. Put standard bulb in and it wouldnt light up at all!
With much checking of fuses and relays I decided to disconnect the battery for 10 minutes to see if it would reset anything.
Re connected battery and it worked!
I think if it detects a short or something it shuts down the control until and it is reset when taking the battery connectors off for 10 mins.
Give it ago you have nothing to loose

Question before I do... If I take the battery off for 10 mins, will my trip computer reset? And will I see any other effects after it, like having to re-pair my phone etc...?
Thanks!
Trip computer will reset (mine did any way). My phone was still paired. Clock will need resetting but apart from that it should be ok.
You may get a couple of lights on your dash when you first start it up but if you drive for about 100 yards they will go off (they are usually the power steering and tyre pressure warning light).
This is normal.
You, Sir, are a
legend! 
It worked!I now have my headlight back!
Strange one that, isn't it? No errors, but the system obviously knew there was an issue... Maybe it's so you take it to a stealer and they charge you
lol.Thanks a lot pal! I'll know what to do in future!
