I am going to add my opinion back in here as ive seen multiple threads dealing with LED, and people jump in saying dont do it, here is a better option that costs far more.
Granted, i dont want to be a problem for other drivers. But I also am not in a position to justify the cost of a huge upgrade. I respect what goes into them, i respect that its high technology. But for me it is not affordable. I installed the LED kit i linked above, took the time to aim them and have been impressed with the output. Call it an illusion to my eyes or whatever anyone wants to. But i have better illumination when driving and not had a single person flash me oncoming. Ive had the LED in for about a month now.
I parked my tahoe between a benz and an infiniti, all 3 with lights on in the pitch dark. Even with the LED the output and glare of those 2 were far more than mine.
All I can say to this is "to each his own". I certainly understand and respect the decision you've made; only you can make it, and if it works for you, that's pretty much all that matters.
That being said, what it comes down to is basically everything I said in my last post. In addition, the experts themselves have written extensively about it here:

I get it. Not everyone has a spare $1k lying around. Matter of fact, this is one of the main reasons I did NOT want to buy a GMT-900 platform vehicle (other than an Escalade): and that is the overall pitiful light output. Weighing in a lot of other things, I finally bought my Yukon, and factored in having to replace the lights. It was still cheaper than an Escalade with 80k miles.
This is one of those "you get what you pay for" cases. By all means, the OP can try the LEDs. It is highly recommended that he not do that, however. Save up for a proper retrofit and do it the right way.
