Product Details

One Two Three: Four! Truth be told, for a bunch of headlight nerds: We could not imagine a more perfect projector. The all-new Morimoto Mini D2S 4.0 Bi-xenon takes the cake in every category. A supreme low beam. A High beam so bright it's unholy. A cutoff line that can't get any sharper. Quality that nobody can question, and an undeniable ease of installation. If we died and went to headlight heaven, this thing would be greeting us at the gate.

Legendary: When Morimoto's Mini D2S 3.0 came out in 2013, it changed the game. When the Mini H1 7.0 launched in 2015, it changed the game. The Mini D2S 4.0 carries on the tradition – and why? Not only does it make the 3.0 look like an old dinosaur...but because it's powered by D2S bulbs; it's capable of taking the awesome optics developed for the H1 7.0 to a whole new level.

Output: We'll just start with the hotspot. It's brighter than any bi-xenon projector we've tested...in fact, it's so bright that it exceeds the maximum amount of intensity allowed by DOT even at 35W. (because #regulations) The beam pattern is extremely wide and flat, with none of the bowing found on the 3.0...all thanks to the beauty in the center of this beast: it's curved cutoff shield. The Kuria Optic clear lens helps produce plenty of color flicker, but also a razor sharo cutoff line that eliminates all glare to oncoming traffic. Last but not least, the high beam. Shaped by the secondary cutoff shield, there's plenty of light reserved for use here to penetrate for hundreds of meters at night.

Physically Speaking: Output isn't the only thing the 4.0 gets praise for. It's clear they've paid a lot of attention to the physical attributes too. The threaded shaft is longer than before, making it easier to install, and it's threads are silky smooth (near impossible to strip). The bi-xenon solenoid mechanism has next to no slack, and thankfully this time, the solenoid input actually plug into the back of the projector. The black lens holder gets the cool “4” cut out too! OEM Quality, aftermarket performance. We like it!

Easy to Install: Picking out a projector always meant striking a balance between a) how much light output you wanted, and 2) how much time and effort you were willing to afford to get it done. The Morimoto Mini D2S 4.0 sacrifices nothing in the light output department while remaining amazingly easy to install. Unfortunately for big ass bi-xenon projectors like the Acura TL, Murano, or FX-R; there's really no reason to cut, trim, and JB Weld the hell out of everything just to achieve output nirvana, and it probably wont be long until they find a new home in our closeout category.

Installation Summary: On a H4-based headlight reflector for example...Remove the headlight lens, insert the threaded mounting shaft through the pre-existing hole in the back of the reflector, add the alignment plate, tightne the lock ring, and re-seal the headlights. For other applications, minimal cutting will probably be involved but you'll find the results well worth it! Check out the Installation Procedure

I see the light!

Duriel Oree Reviewed: 04.08.2017

I did a D2S 4.0 retrofit to my 2016 F150 and all I can say is wow! It throws the light down the road like a spotlight but is wide enough to be in the other lanes of a four lane highway. I feel much safer knowing that I can see the road and I'm also not blinding other drivers in the process. Thanks TRS and morimoto.

ALMOST perfect

Mathias Pertl Reviewed: 03.03.2017

To begin with the good side: The output from these projectors is just amazing. Bright sharp wide. Just brilliant.

Cutoff is ultra annoying! The DOT Style on it's own is .. nja ok .. but the real downside is it's Cutoff-StepUp. It's way too huge.
If you aim them high enough that the left side illuminates the street further than 30meters you will blind oncoming traffic if you are in a right-turn. If you aim them low enough that you don't blind anyone -> you only see around 25 to 30 meters on the left side .. which is even dangerous if you are in a long left turn driving 50 or 60mph.

They REALLY should at least HALF the step up height.
To be exactly the should size it so that 25meters away step up is 25cm high (thats ECE regulation and it really is good!)

ECE Cutoff style (15° angle instead of 45°) would be superb but the stepup-height-reduction on it's own would really help.

Outputs great... hate the cut off

Richard McKenna Reviewed: 02.20.2017

I have to say, these were talked up alot. My biggest problem is the cutoff is too low on the left. I have a dead zone only a few yards out on the left side, and if I aim any higher I will blind on coming traffic. also to note, that cutoff means directly in front of your car down range only has the left side upper section filling in most of your lane. The color and output with the Osram bulbs is great. The high beams combined with 9011 bulbs is ridiculous. Just really not happy with the cut off dropping the way it does. You live and you learn. Otherwise on the car since release, and they have been reliable. high beam motors still work. No water in them.
