The LasFit ones are quality, and BRIGHT. Maybe too bright. Additionally they have replacement OE covers with fans which aid cooling. No experience with Auxito, but if you're looking for bright output, the LasFits will not disappoint.

 

The biggest problem I see with all of this is getting them to actually fit into the housing. It seems that either the "stick" is too long for the projector lens or the fan sticks out just enough to hit the dust cover lip. I'd thought about taking my Dremil and grinding down a little bit of the lip so the bulb will twist and seat. I'm guessing the LasFit Pro's are designed to get around the cover/housing issue. We'll see how long these Auxito's last or, better yet, if they'll come up with a modified bulb.

 

The Lasfit ones have their own dust covers with fans, you do not reuse the OE ones.

 

After reading endlessly about LasFit and Auxito LED conversions for my 2017 Highlander I decided to give it a shot as the Halogens just don't cut it and I've been drooling to switch for years now.
I checked the fitment chart and was given 3 choices. Of course I went for the highest power and newest version the Y19. I spent about 2 hours trying every which way to get them in and they just wouldn't go so I returned them and went on to the next choice, the Q series. Yep, they were supposed to fit as well but after about 45 mins this time I gave up.
Thankfully I'd ordered the 3rd choice which are the Y13 Series at the same time as I ordered the Q series and got them the next day.
After about 35 mins of sweating (102 degree day) and swearing at Auxito I got them in and they seem to be working pretty good.
Not really impressed with Auxito Customer service though.....

Probably would've got the LasFit Pro's but the price is a bit steep to swallow right now.

There are a few reports in the 3rd gen HL forum. Just search AUXITO. This is my report. https://www.toyotanation.com/thread...-m3-low-beam-led-replacement-headlight-in-the-highlander.1719220/#post-14632987
I discuss what I found and why the Q16 does not fit. Auxito know about it. The M3 fits but the cover won't totally go on. It won't go on over the Lasfit either, which is why they supply a modified one.

I read those and considered the M3 after reading it BUT it's not listed as one that will fit nor did Auxito support suggest it when they contacted me. I feel the M3 lumen level is less than optimal and it's just Auxito trying to get any of their products to fit the situation instead of engineering a fix like LasFit did. So far the Y13 seems to be working okay, I guess we'll see.

 

I went with the LASFits. They are designed for the housings of the Highlander with the offset.

Got a 2019 LE Plus in Feb. After some research, I ordered Auxito y13. Low beam H11 and highbeam 9005.
Twice, I spent 20 min trying to install the low beam and gave up. How did you do it? Remove the rubber seal? Did you re-use the original dust cover.

What I did was change the seal for the seal off the stock halogen bulb. Where it catches is right at the top of the housing and the LED fan housing, where the dust cover sits. What I did was to put upwards and in pressure while seating it. What’s funny is the left side went in with little problem, the right was the #%+#%!!
I finally put a bit of Dawn soap on the seal and pushed up and in. I almost got my Dremel to grind down the housing lip just in that area.

 

LEDs will get hot. Ive messed around with a few LED headlights converting them into desk lights and dang do they get HOT.
