After getting an interment error in dipped lights I decided to check the bulb. Have never seen anything like these before, didn't realise that the car had xenon's 

 

Found this on Amazon:

What k should I go for?

Pretty sure you need a D1s rather than a D3s. Is this for a MK2 Superb (as per this section) or a MK2 Octavia (as per your profile)?

 

I'd also suggest you spend a little more and get bulbs from a reputable brand and supplier as there are plenty of fake xenon bulbs around.

 

For example:

- stock, https://www.powerbulbs.com/product/osram-xenarc-d1s-xenon-hid-bulb-single

- performance,https://www.powerbulbs.com/product/philips-xenon-x-treme-vision-gen2-d1s-single

- whiter/bluer, https://www.powerbulbs.com/product/osram-xenarc-cool-blue-intense-d1s-twin

 

Hi, it is for an Octavia!

Then the MK2 Octavia definitely wants D1s not D3s bulbs

 

As for the K rating, that's down to you... I think the best performance is probably in the 4-5k range.

Thank you!

The new bulbs are not working, I've tested them on the other side just to ensure not faulty and they are both fine.

 

Next step new ballast?

Sounds likely

 

You can also swap the ballast from side to side to check it's not wiring related. It's the silver module rather than the black one.
