Anyone know how to tell if i've got a problem with just the lamp or the module?

The OEM bulbs are ridiculously expensive so don't want to go out and buy a new one only to find it's the module.

Also, can anyone confirm if aftermarket bulbs are ok to use, or should I stick with OEM?

Swap passenger and driver side modules to see if its a burned out bulb or bad module.
Aftermarket bulbs are fine. I purchased this for $30 on EBAY about 2 years ago and they still work great.
Use forum search and you will find the whole bunch of info regarding bulbs

PS i actually purchased 6000K-

Hey thanks for the feedback! Why didn't i think of that! DUH!

So with the 6000k bulb youre not getting any errors or messages? And on a side note, would you happen to know of foglights that would match the colour of the headlights? This is something i've been meaning to do so might as well now that I'm getting in there.

Thanks!!!

No error messages should appear, it is just a light bulb. You should get an error message when it burned out and only then. My fog lights are in AUTO mode where they only work when I make turns and only for 30 sec or so, therefore I never thought about it. However, from what I have heard it is not that easy to get to fog light bulbs, you need to remove some cover on the bottom and things like that …

Ok cool, ya i just got the error that the bulb is out. So to confirm I need a D2S type HID bulb? Is there a specific wattage I should be using? I just want to make sure that 1) I'm getting the right size bulb and 2) I'm not getting the something too strong that's going to fry my wiring harness, which I've heard can happen.

D2S is the size that you need, however D2C and D2R will work just as well. I believe we need 35W bulbs . You can buy from Amazon same bulbs that bought couple years back. They are inexpensive and you wont be disappointed with the quality. Any D2S type bulb will work - http://www.amazon.com/s/ref=sr_nr_p_...nid=1248859011
