Had our first rather costly failure on a 14 plate of the head light units led fail, the cost £330 and as it is well stuck together we couldn't get it apart to repair a most likely a penny worth of a component, at least it wasn't as costly so I was told as a BMW rear light similar unit of over £550 worth. Anyone  repaired these?

I assume it is a strip of LED lights in the headlamp unit. Mine is.  Did the whole strip fail or just one of the individual LEDs? 

I don't think all of these mk7.5 fiestas have LED day time lights. It might be possible to use the the non LED headlights on them maybe, I have not tried it.  I would imagine they would have made the wiring plug different to cause grief to anyone  who wants to try this.

 

 

No joy at a breakers yard for a good working 2nd hand replacement?

The hole strip failed, its funny when I first read and was told how reliable LEDs were and could stand a huge voltage range, but when I was trying to put some together that took  1.5 volts so four used in series = 6 volts I was told it needed a stabilised voltage unit or they wouldn't last very long, so its those that fail as they seem they can't stand any abuse from the elements.
