Hyper-Aggressive Look with Huge Improvement in Output

When you're looking for an easy, plug-and-play styling update and improved light output, you just can't go wrong with Morimoto and their XB series LED Headlihgts. Each headlight features a unique quad lens design and uses powerful LEDs to generate far more light output than the factory halogens or other stock-replacement headlights. The four lenses are set in a black housing with aggressive styling that is sure to turn some heads both at night and during the day. The design features a parallel row of amber LEDs surrounding the perimeter of the white DRL, running in sequence around the outer vertical edge of the housings. If preferred, the amber LEDs can also be setup to run as solid on/off style signals too. Each light produces an extremely powerful 2,600 raw lumens for incredible off-road visibility.

High-Quality Construction with Plug-and-Play Install

Morimoto builds each of their XB LED Headlights with both quality and performance in mind so that you get awesome light output for the life of your truck. The headlights' quad beam configuration uses the upper lenses for the low beams and the lower two lenses for the high beams. The housings are made out of lightweight, yet durable PPS plastic and feature embedded aluminum heat sinks to provide adequate cooling for the headlights. The outer lenses of each headlight are made from UV-coated polycarbonate that helps keep the lenses looking clear. The headlights come with a plug-and play wiring harness that makes it a breeze to get them up and running on your truck. The headlights are rated IP67 waterproof for all-weather durability. These headlights are DOT and SAE approved for street use.

2019 Ford F-250 Super Duty

I bought the Morimoto XB headlights for my 2019 Ford F-250. They’re much brighter then my old halogen headlights. If you want my honest opinion, they’re not worth the $1750 I paid for them. The sequential turn signal didn’t work on my headlights only the standard. That was fine because that’s what I wanted to use anyway. The passenger side headlight is a pain to adjust the beam. The battery and stuff is in the way so you have to keep taking the headlight out to adjust it. The power cable to the fuse box was a pain. I had a fuse in the way so I couldn’t plug it in where it was supposed to go. I took the fuse out that was in the way because it said it was for the fan #3. So I moved it to the empty fan #2 spot. I haven’t noticed any problems by doing that. But I was able to plug in the power cable. The headlights don’t work right in auto. You have to turn them off and on manually. That’s also a pain! But the biggest thing that really sucks is you pay $1750 for these headlights and if a bulb goes out you’re not able to replace it. So you’re pretty well screwed after 5 years when your warranty is up. Paying this much money for headlights you should be able to replace the bulbs.

Lights look great. They are much brighter than LED bulbs in the factory housing. The DRL's are bright and the sequential turn signals look awesome and are also very bright. The only dislike I have is the adjustment screws being on the backside of the housing. It makes getting the lights pointed correctly a pain.

I love these lights! I had a few issues getting them installed though. There's a problem sometimes with the plug ins that will cause the lights not to work. After corresponding with Ryan at Stage 3 and the manufacturer, they were able to trouble shoot and figure out the problem. Thanks again to Ryan and now on to the next upgrade!

The Morimoto headlights are as good as it gets! Great quality, outstanding light output, and a 5 year warranty. Not to mention they will definitely change the appearance of your truck in a very good way.

These lights are an incredible upgrade from Halogen! Pretty straight forward to install. Make sure you adjust your lights for other drivers as these are crazy bright. If you’re going to upgrade your lights, do it right and get the Morimoto XBs!

Excellent upgrade from halogen! Unbelievably brighter and all of the sequences are even better: I also had an issue w/ one of the lights. The customer service was amazing on the issue. I had a replacement sent to me in 2 days. The functionality of the head lights is excellent and the look of them, cosmetically, is the best part!!!! When you’re driving a $50-$100k truck… You’ve got to go all in!!! I highly recommend these.

Will these void a warranty for new truck?

Asked by: Jeff - 3/2/2019

In general, basic bolt-on parts like these headlights will not have an effect on your truck's bumper-to-bumper warranty given a proper installation. That being said, all warranty decisions are up to individual dealerships, and your best bet would be to talk to your service advisor directly about what kind of leeway they give.
