Hi folks. I have been having a bit of a time of it with my bi xenon lights. The left hand side one started strobing, and after a bit of reading up I decided it was the bulb, took it to my helpful garage who checked and it turned out the ballast had failed.

 

Bought new ballast , fitted, bulb works but slightly dimmer than the other bulb, and 1 week later the same lamp stops working.

 

What are the chances that the sketchy ballast stressed my bulb and it was just a matter of time before it failed.

 

Not looking forward to paying for the labour time again.....

Buy new bulbs, in the meantime swap the bulbs around and see what happens. I'd say the bulb was gone already and you paid for a worse ballast + labour for whatever reason.

 

Btw, led bulbs are an option in d3s package lately. I got a pair on mine now

Likely ur original ballast that failed had caused the imminent failure of the bulb, aka all that strobing.

 

When changing xenon bulbs, it's good practice to change both bulbs at the same time, otherwise the new one will b off a different colour temperature to the old one.

 

As the mentioned above - u can change to LED bulbs instead, if u can.

I recently switched from xenon D3S bulbs to LED D3S bulbs (JW Speakers brand).

A big improvement, plug & play. No errors or issues.

 

 

 

 

Do you need to remove the bumper to change the headlight bulbs to get access to the headlights or do you need to go through by moving the wheel arch to get to the back of the headlights?

No need to remove bumper.

Removing the wheel arch liners gives U plenty of access behind the headlights.
