Product Details

Morimoto: Has always been our go-to-guys when it came to HID, and when they released their line of LED products, we had our doubts. Performance left a little to be desired compared to some of the more refined models on the market. BUT (and thats a big BUT) that has since changed with the much more mature, refined second generations of each model they offer. While in all-honesty Morimoto didn't exactly nail it the first time around on the LED bulbs, what we have from them today is about as modern as it gets and much more in-line with the quality and performance we've all come to expect from the brand.

So What's new with Version Two? Updated optics help distribute light in every direction, most notably improving rear-ward spread. The newer drivers are compatible with a wider variety of vehicles and have better contrast between low and high intensity modes. We dig it!

Featured: In the October 2015 issue of DSport Magazine alongside LED offerings from Philips and Osram. Morimoto is the benchmark in aftermarket automotive lighting!

Instant: Beautiful, bright light. Nearly infinite life span. Great for signal, marker, brake, and tail lights. The XB LED bulbs are an instant upgrade in the looks and performance for the lighting on your car from bumper to bumper.

Tradition: As a manufacture best known for their optics in headlight projectors: Naturually Morimoto's XB LED bulbs feature a polycarbonate optical lens. With perfect clarity that distributes the light from it's six LEDs in a 360 degree pattern, these bulbs will radiate light in all directions without any dark spots.

Protected: Heat management is crucial for reliability when it comes to LEDs. Using just six LED chips to produce peak output, the XB LED generates less heat compared to other bulbs that sometimes use up to 48 chips. The CREE XB-D LEDs are mounted inside the lens, which sits atop a ribbed aluminum heat sink. Inside; an integrated thermal resistor reduces output as a secondary level of protection.

Can-bus: The XB LED bulbs are can-bus friendly and should not cause "lamp out" errors in MOST applications. If however your vehicle requires more resistance, we recommend using the Morimoto HD Load Resistors which will instantly and safely resolve any issues there.

CREE LEDs: For more info on what's inside, you can download the CREE Data sheet on the emitters that Morimoto uses in the XB LED bulbs.

Great product

Milos Reviewed: 01.24.2016

I bought a pair of these for taillights on my 2014 Mazda 3 GT. The car came with standard bulbs which were totally unnoticeable, even at night. It looked as I had a pair of candles and every Mazda 3 owner will confirm.
So I bought these and I am really satisfied, they pop right into place, no special cutting or DIY work required, plug and play.
The amount of light is just right, they do not bleach the red color of the taillights, it's a deep red and the non delay feature of LED matches with the 3rd brake light.
I would recommend this product to anyone looking to upgrade the look and visibility of their car and especially 2014 Mazda 3 owners.

Good job Retrofit Source!

The best switchback turn signal on the market

Aswin Reviewed: 09.28.2015

Look no further, this is the best. The white is white, no blue, and very bright. When it blinks, color is amber, true amber, not yellowish like others on the market. For resistor, you can get it on for $5, just as good. When you hook it up, clip resistor to black and red, if you have 3 wires leave blue or green alone.

The best switchback turn signal on the market.

This is the best switchback turn signal on the market.
White light is white and bright. Amber when blink and the Amber light seems brighter than white. And its real amber, not yellowish like other LEDs on ebay/amazon. you'll need resistor so it wouldn't hyperblink, I got the resistors on Amazon at $5 each. If you have 3 wires socket, clip black and white with the resistor, leave blue or green wire alone.
