DMEXD1S Xenon HID Headlight Bulbs 4300K Warm White 35W 66144 66140 85140 85415 Replacement - Pack of 2(NOT fit Halogen Headlight Assembly)

These HID replacement bulbs have made such a difference for me as I was initially not sure why my lights were not working since both my low and high beams on both sides quit working all at the same time. So I figured there was no way it could be the bulbs because what are the chances that not one, not two, but FOUR bulbs all burned out at the same time? So I did some research and I bought a single headlight replacement ballast thinking that it needed it, nope it wasn't that. Also did things like checked fuses and relays, basically did the whole 9 yards when it comes to trying to get the issue resolved because I had been driving around with only fog lights being used in place of regular headlights since fog lights were the only set that still worked.THEN I found out that my low beams and my high beams used the same bulb on each side, they just tilt to a different angle to light the way when switching from low beams to high beams and vice versa. So then I thought that the bulbs most likely did just burn out at the same time afterall, since it was only 2 bulbs that needed to fail simultaneously rather than 4 like I initially thought.So I went online, ordered these ones since they said they would fit my 2011 Jeep Grand Cherokee Overland Summit, and they were also going to be delivered same day as well which was a deal maker for me because I was ready and determined to have working headlights again!They came about 5 hours later, as promised, the packaging was great as it was appealing to look at and it also kept the lights held tightly snug between the foam in the box to prevent shaking around and possible damage to the bulbs. The price on this set was also unbelievably affordable compared to OEM and other familiar names, and most importantly was that the price was literally a fraction of the cost of the auto store replacement hid bulbs, yes 29.99/a set of 2 sure does beat 139.99/1 bulb at the local auto store!2011 JEEP GRAND CHEROKEE OVERLAND SUMMIT — They fit perfectly in my vehicle, however I think that hid bulbs are typically rather difficult to replace in most vehicles compared to standard bulbs just due to the precise placement and to prevent them from being an easy target of theft since they are quite expensive, and because of how spendy they are I'd actually prefer some level of difficulty accessing the bulb's location in the vehicle.I got the 6000k and they are very bright, much brighter than my previous set which it is unknown if they were the stock set. I often times get brights flashed at me from vehicles passing me going the opposite way as they assume that I have my high beams on, when I only have my low beams on so that should emphasize how bright they really are! The 2 year warranty is just a great bonus because I'd purchase these bulbs again if they were to burn out prematurely especially since the purchase of 2 sets still doesn't even add up to the amount I might've spent for just 1 had I purchased them at an auto store or if I had opted for a more well-known brand.Still undecided? Well....THE SHORT ANSWER is that these HIDs are most definitely worth it so if you're still up in the air, trying to decide whether or not to opt for purchasing HID replacements from DMEX, you won't be disappointed at all if you do! They don't get more affordable than this for a quality product and also the 2 year warranty pretty much guarantees that quality if you still have any doubts! I will update this review with photos soon.

Didn't realize my Mercedes M-Class had these lamps with transformers built into the base! I discovered this when one went out, and I checked and both were original lamps (I have over 200k on my M-Class.) I've always replaced both lamps when one fails, that way you know the life of them. These were easy to install, were bright, clear and had that wonderful piercing HID beam! I saw they ahve a two-year warranty, so I will definitely report back if I have any issues.

I've only had these bulbs for about a week so I can't speak on longevity yet, but I have seen enough already to be impressed with these bulbs.First off, installation in my 2011 Dodge Durango Citadel wasn't the easiest I've ever done but it wasn't terrible. You might be able to reach inside the access port in the fender liner without removing the wheel but I suggest removing the wheel anyway. You'll be glad you did! User clean gloves (white cotton, latex, nitrile, etc) when installing the bulbs and be VERY careful not to touch the glass at all (oils in your fingerprints cause weak spots in the bulb that can shatter when they get hot)Once the bulbs were installed there was a slight delay the first time I turned them on where the bulbs had a dim blue glow but after a few seconds to warm up they came on. The brightness and color of the light started out very similar to the factory bulbs then became slightly whiter and visibly brighter after about 30 seconds. This isn't unusual with this style of bulb, unlike standard halogen bulbs, the Xenon projector bulbs often have a break-in period. I left them on for about 10 seconds then turned them off and allowed them time to cool completely. After that I turned them back on and this time they came on immediately and again increased in brightness slightly after about 30 seconds. I cycled them again and the third time they came on immediately and were at full intensity by 10-15 seconds. From then on they have come on and been at full intensity in 3-5 seconds.As I mentioned earlier, these bulbs started out with approximately the same color and intensity as the factory bulbs but became slightly brighter and whiter as they warmed up. This continued while I was breaking them in and now they appear much brighter than the factory bulbs and exactly the color temp I was hoping for. They are listed as 4300k but I would guess them to be between 4700 and 5000k. No blue tint at all and not a harsh white, just a very nice white on the lower end of the temp scale. Needless to say I couldn't be happier!Now for the best part...the value! The factory replacement bulbs are over $100 EACH at Autozone and these bulbs are 1/3 of that price for a pair. I always replace the bulbs as a pair (guess I'm OCD but the slight variance in light between a new and old bulb would drive me crazy lol!) so figure $200+ vs $34 and it's a no-brainer. You could replace these bulbs each year for 6 years (not that I expect to need to!) and still have saved money.
