[SMOKE EM IF U GOT EM!!]

Are you sure your modules are no good? Positive that you need new headlights? Might just need some new bulbs. Your best bet is to get a professional to look at it, that you trust and is knowledgeable w your car, or someone here on the boards so you don't get hosed for stuff you don't need.

These headlight housings have:

One bulb for hi/low xenon beam
Seperate bulb for flash to pass/daytime runnin lights (on our years)
Turn signal bulb
Angel eye (corona ring) bulb, which are a bitch to change unless you take the wheel and fender liner off

And each housing has an igniter ballast for xenon bulb
And each housing has an adaptive headlight control module (for lt & rt motion)

It could be a simple fix before you have to condem the lights and spend thousands. So my advice is get it looked at if you don't feel confident doin it yourself. But there is a lot of good info on here to guide you I you decide to DIY

Good luck whatever you decide
