Hello, 

Just noticed my Octavias xenons flicker and dime a bit so maybe the bulbs themselves are going ? It's 2008 and the bulbs are osram xenarc electronic 66142 (4300k I think) when I searched it was mainly 66144 came up at 6000k but I assume these will fit too as the original is hard to find. Thanks

The temperature colour does not affect the issue you're facing but if both bulbs have started simultaneously to flicker I would think there is another problem located regarding, electronic one possibly.

Usually one bulb first goes and then sooner or later the other follows..

A good place to search for new ones is the power bulb UK and lot of variety..

Was thinking that not sure where else to look unless it's the igniter ? Not very familiar with xenon kits bit can't think of anything else at the minute

Assume it's an OEM original?

Yea from Skoda in the factory 

I suppose these would be the ones that would suit mine? I would say it's a ballast fault which is the part the bulb plugs into ? I'm clueless in this field haha
