Wow, thanks for the tips!
That's not that easy to be 100% in what you are going to buy....

 

any chances of taking ALL these guides and combining into one in the first post? also I don't know if I missed it but is there an explanation for 35W, 55W and digital ballast difference?

 

So are you guys are saying projector headlights with HID kits installed in them are no good?? I love the HID look but I'm new to the HID world really and been reading stuff for the past couple days but it's so much info. I just wanna do it right and not be the cause of death.

 

I've been looking at the projector headlamps you can buy and buy an HID for it. Some kind of plug and play thing, but I saw a few times in here that it isn't any good? I'm not really understanding it, but then again I never worked with HIDs before. So if I buy these headlamps then what should I do exactly?

 

too much info in the op

which ones are you buying? any HID ive ever bought was plug and play

 

2005-2010 Chevrolet Cobalt Halo LED Projector Black : Spec-D

These are the ones I'm looking to buy. They sell the HIDs with it for like an extra $150. I just want to make sure I'm not wasting my money on something that's gonna suck lol.

you'll be good with HID kit no problem. just make sure you get the correct bulbs

 

The light output will be better than stock with just the bulbs, but still not as good as a full on retrofit, and you'll be blinding some oncoming traffic with some glare..
