Anyone using LED D2S hid bulbs??

I'm very interested in the LED D2S replacements that are available, does anyone have any experience with them?? I see I can get them off eBay and Amazon from $90-$150.

On the recommendation of a friend who uses them, I purchased these a few weeks ago...

http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

Say what you want, but at $40 shipped for the pair, they are working out quite well for me. They're much brighter than the factory D2S I pulled (granted they were almost 10 years old) especially in the high beam mode. I drive on dark secondary roads among tall trees every night and these have increased my visibility and safety by leaps and bounds. The naysayers on Amazon bought the stupid version of the bulbs. Anything above 5000k and maybe 6000k will not illuminate the road well. Those buyers are uninformed and went for the bling.

I chose the 5000k color temp which is slightly whiter than the 4300k of the factory supplied Philips bulbs.

I did a lot of research ahead of time as I read "cheap bulbs burn up igniters" and a bunch of other BS, but not a single documented case surfaced in my research, so I discounted it as hearsay.

I ordered D2S but received D2C, which is just a universal mount that fits multiple applications. One of the first reviews you'll read from an Audi owner states he had to modify something. I can't see how that was even possible after installing them. Took me all of 10 minutes per side to do, mostly because I don't have little boy hands.

BTW, in my experience, LED is far superior to HID. A friend installed a system in his motorcycle and it saved our lives one night in Death Valley. I so wish I had a headlight assembly that would accommodate a system like that on my bike - outstanding!

Your car presently has halogen headlight assemblies? If so, you need H7 for low beam bulbs and you must triple check that these LEDs will fit in there. They are much deeper at the connector side than standard H7 bulbs.

http://www.sylvania.com/en-us/applic...n.aspx#fldYear to find the bulb you need.

It's got aftermarket depo projectors with halogens for the high beams and HID for lows. I will have to do some measuring, to see if the LEDs will fit, cause they are rather large as the specs state. Sounds like they are super bright too

I do not think you can just throw an LED bulb in an HID housing and call it done. You're going to have to see if the LCM (light control module) will work as it is, or if you have to swap it for a halogen version, or recode HID to Halogen. I'm not sure about that part, but I do know from past reading, some extra steps are required.

Furthermore, the lens on an HID is different than a lens on a halogen. You may not get the result you want from that either.

If it were me, I'd spend $40 on the HID bulbs I bought and give them a try. Granted, I cannot speak for longevity, but for the price it was worth the gamble for me and I do like them.

You HAVE to use the bulb the reflector or projector is made for.

Halogen, xenon (HID), and LED bulbs all have different focal points and beam patterns. If you put a different bulb type in a reflector or projector that it was not meant for, you will have sub par output.

You will lose light output and most likely create hot spots that will blind other drivers.

+1 for Osram CBIs
