D4S HID Bulbs,Xenon Headlight Replacement Bulb 35W 6000K Pack of 2

First off I have to say I decided to get these simply because all my other cars fun Beamtech Fanless LED kits and they are absolutely fantastic, color and brightness is spot on! Never an issue with durabaility or failures, have used them for past 4 + years.Anyhow back to these HID bulbs, upon install I immediately noticed the light output was not near the same as stock HIDs that I removed. Reason I was replacing is due to age of stock HID bulbs. The break line is still in the correct location however the light is so "scattered" that it really doesn't put much light on the road, even with my adjustable headlamps. Thus with it tuned down to 1 on tilt it does help alittle. Now after a week and half the right bulb has started to turn alittle yellow which is super odd but the left is still "white" not sure what's up, perhaps the bulb is defective already?? Who knows but for now I'll leave them in and see what happens to the yellowing one.So for the price, I supposed I got what I paid for? But really has much higher expectations due to 5 star experience using the LED kits.Would I recommend them? Honest I have to say not so much, if you need a quick fix to pass inspection or something then yes! If not I would say pay more for some Morimotos.Just my 2 cents. Hope this helps.

I installed these on the wife's 2012 IS 350 C a few months back. As most reviews state about this vehicle is that it takes 30-45 minutes to install. Simply because you need to remove a few items to access the headlight bulb area for replacement/removal. The lights have performed well. No cutting out or failure. The light is on the cool blue side, which I like. For the price you can't complain. Give them a try.It has been six months and the bulbs are still working flawlessly.

I can't say on Longevity because I just started using them.

Both bulbs don’t match the color

Great improvement in brightness
