Morimoto XB Headlight Issue
Today I noticed that none of the passenger side headlights are working. LED frame works - just not the 4 bulbs. Now that it got dark I started to play around with them - and they will randomly come on - and other times you can turn the lights on 30+ times and they won't come on. The startup sequence also doesn't work on that headlight now. When the headlights do come on - they are just on - the drivers side does the sequence though.
All others lights work - signal/DRL etc.
I pulled the headlight out to check for bad connections and everything looked fine - unplugged everything and reconnected. When I was doing this testing the connections the lights were on. Tried turning them off/on about another 15 times and they turned on every time so thought I was good - bolted the headlights back in and put the grill back on etc. Lights were still on. This time as soon as I closed the hood - boom lights turned off. I then went back to the cab and turned the headlights off and on about 15 more times - and then they came back on. Turned the dial off and on again - no headlights. Tried playing around with the fuse relay connection - didn't change anything at all.
Totally stumped what is causing this - other than a faulty light. Pretty disappointed considering these were almost 2K.
Has anyone seen/heard of this before? I bought through Headlight Revolution and emailed them. Haven't heard back yet.
Hopefully HR will take care of it!
I installed the Morimoto's about a year ago. 2 months ago the right side did the same as yours.
Headlight Revolution sent me a new harness. This worked for a month and thenthe right light started going intermittently on and off. Also the lens housing started to vibrate.
Sent videos to HR. They had me pay a deposit and sent me out a replacement set. I installed them today.
They are worse then the originals. Alignment is terrible. The first set were spot on right out of the box. Also left light correctly cycles thru the cycle sequence, the right one does not.
I think I'm done and will be putting back my halogens. Seems Morimoto has some serious QA issues going on.
For now I just want to get my $1000 deposit back, I do a lot traveling with an Airstream and cannot afford to have lights out in the middle of no where.
I did install Rigid Grill Mounted lights which can fill in, in a pinch. Also installed Rigid rear lights for increased light to the rear.
I think I'm kind of done with Morimoto's.
Headlight Revolution has been great - Morimoto's seem to be a problem. One I cannot afford to live with.
Failed right light
Replacement lights - alignment is way off out of the box.
Rigid grill fog kit
Rigid flush mount rear light kit
Rigid rears at night
So with the new replacement does the light actually work? Both of mine needed significant alignment right out of the box as well. Not ideal but I would take that vs. a defective light.
We are pulling a 5th wheel in Phoenix and about to head to Florida next week so the worst possible timing.
What a f**king joke. $2000 headlights and this is happening? I bought the best so I wouldn't have to deal with **** like this.

We are heading to Scottsdale Barrett Jackson in Jan and I cannot be having light issues. With my Rigid and LED's in my fog 's I'll probably stick with the factory stuff. The Morimoto's seem to have some serious quality issues.

Still trying to get a return authorization from Headlight Revolution to return the original defective ones and get my $1000 deposit.
After all of the hassle I boxed up. the new replacement XB's and put them in storage.
Went back to the factory halogen headlights with Sylvania Ultras.
Heading to the desert in Jan and cannot take a chance with lights failing.
The Rigid lights in the center grille and the LED fogs give me plenty of light. Sylvania Ultras installed in the factory headlights.

The Ford LED's are not plug and play.
You will need a kit like the one Morimoto makes. Given all of the trouble I've had with Morimoto's I would past. The other option is to source harnesses and ballasts I think. There are threads on the forum if you do a search,

You many also need to make changes to the Forscan settings to get them to work.
Moving to LED. will consume you. For me I had enough. I could pull the grille and lights in my sleep. You may wish to try the Sylvania Ultras. Orileys has them,

They are not bright white but they do appear to be brighter with a broad light pattern.
I did try these but was not impressed. Maybe they have improved them.

I have OEM LED, as for the harness theres plenty of companies making them and then just a few forscan changes i believe?

Hope ive been of some help. This would easily be the best way to get LED lights.
That's probably why the Morimoto sells. But I've seen several complaints on this forum so I think that would rule them out for me.
I did LEDs from Amazon on my 2018 F350. Best $100.00 I spent (2 sets of headlight bulbs plus 1 set of fog light bulbs). Took about an hour to get everything in and put back together. I couldn't be happier with my headlight setup.
I do want the grill lights you have there.
