the ballast is over heating and turning off till it is cool enough. Get a new ballast and add in a relay harness.
I'm a bit shocked that the fuse upgrade was suggested. There is a reason why the factory calls for a 10a fuse. The wiring can't handle the over load power that is is now forced to support. I know this is not the first time people have done this but IMO you are playing with fire.

 

But if the ballast is overheating shouldnt the bulb turn on again once it cools down? Once it goes out it stays out until i shut the lights off and then turn them back on. I installed them using an install guide on this forum and the guy said to use 20 fuses because the HID's need to draw more power when starting up. Do you suggest switching back to 10a? Why all of a sudden would the ballast start overheating after a week? Thanks for your help btw

 

Once it goes out it stays out until i shut the lights off and then turn them back on

this is because there is still current going into the ballast.
When you turn the lights off you kill the current and it has a chance to cool, and 'reset' itself.

Do you suggest switching back to 10a?

Absolutely. There is no need to run a 20a the entire time. just wait the extra 20 seconds for the bulbs to warm all the way up rather than forcing them to high more current. thats a good way to start an electrical fire from a melted wire or connector.

Why all of a sudden would the ballast start overheating after a week?

Because it's getting to much power during run time. Similar to overclocking the cpu on a phone or computer, you wear it out faster. Could also be dependent on the quality of the kit from the get go.

 

2kg covered it all.


When you switch back to the 10a fuse and by chance you do pop a fuse then I go back to my orig statement. Add in a relay harness. The harness will pull power directly from the battery and the stock wiring will be relieved of the overload they are trying to perform now. Upping the fuse amp as already stated is a bad idea it may cause everything from a melted wire plug to burned wires to god forbid a fire.
A relay harness is about 12bucks it's not bank breaker.

 

^ what they said

be real careful this is electronics... you dont want to start a fire do ya?

 

Thank you everyone for the help. I just switched the fuses back and if i do end up blowing a fuse ill buy the relay harness. So is this overheating a result of a faulty ballast? And the only thing i can do is replace it? The kit is pretty high quality, not top of the line but also not ebay crap. I got it off of a guy that closed his performance shop a couple years ago and is slowly selling off his remaining product so im not sure how easy it will be to find a replacement ballast.

 

swap the ballasts from one side to the other. If it starts happening on the other side, yes faulty ballast. If it stays on the same side then there is an over load from your factory harness or the HID bulb causing the ballast to overheat. It could be a bad bulb with a large amount of resistance causing the ballast to over heat.

Any ballast will work. If you continue to have the issue I would suggest removing the kit and getting a new one if the guy you got them from has any others left.

What works for one my not work for someone else. There might be a bad factory ground with some rust or it may be arching causing a higher resistance on the driverside causing the higher load and heat.
So what someone tells you works for them my not work the same for you.

 

Alright I will give that a shot tomorrow. Thanks again!

 

Okay so earlier today I went to swap ballasts to determine whether it was the bulbs or ballast, but after switching back to 10a fuses both headlights worked? Now before trying them I did play around with the wires but I really don't think that's what fixed the problem. But.. Now when I turn my lights on, my clock, deck and other interior lights dim and when my iPod is plugged in it won't play... Can this be solved by adding a relay harness as suggested?

 

turning on your lights the dash lights should dim unless you have your dimmer switch set to full brightness.
as for the ipod issue, that sounds more like a radio issue than a headlight issue.
for sh!ts and giggles did you put the 20amp fuse back in and see if the ipod worked?

 

It's been said before many times. You should ALWAYS buy a harness when you are installing an aftermarket HID kit.

This will prevent you from potentially frying your OEM harness and will enable you to trouble-shoot any issues more easily, since the kit will be plugged straight to the battery.
