HID Headlight turns off during spirited driving
 

...

Try swapping bulbs left to right and see if it happens on the driver side, or try switching to oem bulb. It could be a faulty bulb and I'd contact the seller.

If you've swapped the bulbs already then I'd bet it was something to do with that

...

Check connections between bulbs and ballast. Also swap the driver side bulb to the passenger side and drive how you were before. If there is no problem then its your bulb. if there is a problem then definitely you ballast.

I may have found the problem... The connector at the bulb from the ballast is burnt/melted. Let's see if Subaru will fix this under warranty

I think you get a bad aftermarket HID bulb or the moisture leaks and cause the burn.

the dealership will probably say that you didn't use a genuine OEM product and went aftermarket, which caused the failure then deny your warranty claim. or they might not care and fix it for you. 50/50

...

This is why you don't use cheap HID bulbs...

Just because we price our products fairly doesn't mean they are "cheap" or low-quality.

They are produced by CNLighting who also manufactures "Morimoto's" XB HID bulb replacements.

OP, it honestly sounds like they aren't seated properly, but please give us a call: (314) 205-3033

We will help you troubleshoot this issue, and provide warranty replacements if needed

We appreciate your support and we want to make sure you are taken care of

Thanks,

I will be giving you guys a call after I get my connector fixed as it is melted and Im going to see if Subaru will replace them. Thanks for the quick response!

Talk to Glenn at Marostica, and play dumb ;)
