Loving the quality and brightness
This is really a great company to work with! I bought the wrong lights (because information on my car is tough to find) & they gladly helped me twice & refunded me where needed, with a smile. Their products are very professionally built & packaged & are gorgeously boxed & presented. If you need lights, go with Auxito!
I bought the Y19 leds for my Prius. Wow, what a difference! They made night driving so much better. Very clear lines of light and dark with excellent clarity in all the space meant to be filled with light. No one has bright-lighted me while using these either. I got these in Oct of 24 and several months went by and the passenger side low beam still worked but wasn’t very bright so I ordered another pair. I repaired the light myself by striking the headlight housing like any self respecting redneck would. Now I had an extra pair of bulbs I didn’t need, however a friend who is a widow did so she has all of the afore mentioned benefits for her Honda CRV. Of course after that the condition reappeared so I’m ordering another pair to install and keep the drivers side for a spare. Hope this pair and my friend’s pair hold up.
Headlights and fog lights are super bright now. I can see everything at night no issues there. Bright white. I just hope they last as long as advertised
It's essential to get the rotation of the bulb correctly set before aiming. The left side of the pattern is perfect for not blinding oncoming drivers (if aimed correctly), but the right side has scatter, and it's angled and quite high, making roadside signs pop.
The left side to the middle is what's important for aiming. For most cars, this is two inches below the distance between the ground and the dimple on the light housing @ 25ft from a vertical wall.
Set the rotation first, then aim at 25ft, paying attention to the obvious horizontal line L to the middle, and you'll be dialed in.

Love them the brightness helps me out alot while doing my routes everywhere I go
Put these in to replace my standard halogen bulbs. Wow! The difference is really night and day. I'd guess they're 4x as bright as the halogens, and make me car feel like a new car. I'll be getting these for my high beams as well very shortly.
My first order with Auxito was for headlights, fog lights and 194 interior lights. When I had exrtra 194 bulbs I decided to swap out my license plate lights and also change the interior lights on my 2021 Honda Pilot. Afterwards, I noticed I missed the bulbs on my rear hatch light, and I also needed a different bulb for the cabin light on my Tacoma. (It needed a 578 bulb) So, I ordered some more 194 & 578 bulbs. Every order is shipped right away and the cost is reasonable. All the LED replacements were pretty easily installed and they all look good. Only minor challenge is getting the polarity right on the 194 bulbs, but it is easily corrected in a few seconds by removing the bulb, turning it 180 degrees and plugging it back in. My next order will be for back-up lights. (Maybe when it's warmer outside.)
I am pleased the warranty was honored, and the fog bulbs were so good that I also purchased a set for my headlights. The headlight does have some humming sounds, but that can be ignored with the stereo playing.
I replaced the stock D1S a few years ago with '200%' brighter HID bulbs. These Auxito LEDs have a higher colour temperature and are noticeably brighter. I was a bit concerned they may be too bright, but they are nice improvement.
