These LEDs make such a major difference in visibility over the older halogen bulbs, plus add a newer fresher updated look to my Tacoma! I just had to cut back the rubber dust boot to make it fit. Other then that pretty straight foward.
Here was my installation steps:
(1)-Remove the round metal ring from the new LED bulb and attach it to the headlight plastic housing and attach the metal springy clip to hold it in place (just like you would when replacing a halogen bulb) but at this point the LED bulb is not installed yet, just the round metal ring.
2-I Cut the rubber boot like you see in the before/after picture
3-Slip the rubber boot onto the LED bulb then slide the LED bulb (with boot) onto the metal ring that are in place on the plastic light lens. Keep in mind you have to line up the slots on the LED light with the 3 bumps on the rings the when pushed in all the way give a twist so the LED it ends completely vertical inside the housing and the wire plug outside the housing is at the bottom.
4-Plug and test and you should be good to go.
5-FYI- I pulled the battery out for more room on driverside and
unscrewed the windshield wiper reservoir on the passenger side and moved it just enough to make it easier to slid the bulb in.

I installed these during the day but you can still see the difference in color between the new LED on the driverside and the old halogen on the passenger side!

I spent nearly more than one hour trying to get this bulb to work with the existing rubber dust cover on my 2008 CRV. The design of the cover is made to seal up to the body of the original halogen bulb. What makes this install difficult is that when you try to push the bulb into the retaining ring, it releases the locking clip and the entire thing comes apart. In the process I somehow lost the clear o-ring that is needed for this bulb to press fit and turn in place to secure it. Very frustrating experience. I even had to modify the rubber dust cover so that the bulb can press fit back on the locking ring.

***Updated Review***

When Lasfit read my review they were quick to provide a solution which led for an easier installation. Here was my email back to them:

The replacements you sent worked perfectly! I followed the instructions as outlined in the email I received from your customer support and I was able to make the installation happen. I’m quite impressed with the huge difference between the old halogen lights and the Lasfit LEDs. The difference is night and day literally. The beam pattern is perfectly aligned between both right and left side LEDs. No additional adjustments required (just made sure that the alignment was point in the correction orientation and square to the installation housing).

I can now feel safe and confident knowing that my path at night is better lit and other cars can see me approaching as well.

I have yet to replace the old halogen fog light bulbs in the vehicle as it doesn’t align well with the LEDs. It looks weird but so far it’s doing its job.

I am still using my Lasfit interior LEDs on my other vehicle. 5 years running and still going strong.

Thanks again for the great support! This shows that you guys value quality of your products and listen to your customers feedback instead of focusing on revenue which always kills quality (look at GM, Ford, Chevy- basically all American made cars).

Turned the stock dull yellow lights that were terribly dark for night driving into a bright safe night driving experience. Plug and play. Highly recommended. I only had to modify the rubber boot cover slightly. Front view photo shows right headlight with new Lasfit bulb and left with stock bulb.

Finally gave my 24 year old truck a face lift with these. It is a massive improvement over the halogens. Customer service is very helpful too. I am extremely satisfied with the performance and the price. pro tip to save you some time: install them exactly how lasfit says and adjust your assemblies.

Absolutely best LED Headlights we have tried in out Toyota 4runner and Tacoma. Not a single person flashes us for highbeams. And absolute must for anyone living around deer areas. You can see the deer and have plenty of time to react. Insur. Companies should require this quality og headlight, be alot less wrecks due to animals and people crossing the road. Super helpfulfor those who drive in city at night and in the country side. This is my 12 set Ive installed, not a single custome has come back due to not liking them. Pictures are from dusk. Super nice to have

The fitment and quality are great. RECOMMENDED

I was recommended to LASFIT by a friend after having try using other LED bulbs. Having just recently got them I didn’t waste any time installing ! I was a little hesitant to try this brand boy was i wrong !!! Enthusiast off-road than I am. We understand that a great pair of headlights can meet the difference between coming home from a great day of trail riding to a day of the disaster. I feel super confident in my abilities to do night trails with these headlights! They are so bright and the straight plug-in play very easy to move and adjust once on headlight!! 10/10

I was wrecommended to LASFIT by a friend after having try using other LED bulbs. it just received giving me the correct amount that is required for operating so naturally, I was a little hesitant to try this brand boy was i wrong !!! They are so bright and the straight plug-in play very easy to move and adjust once on headlight!! 10/10

The installation was fairly simple. The instructions could be clearer, though. I figured it out eventually. Some have rubber cover and it needs to be installed before the "bulb" with the opening pushed over the collar where the bulb fits. Make sure to mark the TOP side of the bulb, so you can "rotate" it in with the proper orientation (the wire hangs at the bottom). I think some customers complain that the light points in the wrong place. That sounds like it needs to be rotated/aligned. The light is brighter than the original lamps, for sure. I actually like the white color than the yellow/orange. The Daytime Running lights are brighter as well. The picture shows old/new comparison.

I purchased these to replace my factory bulbs and they are a huge improvement, installation took 5min. I had an issue with one bulb and customer service was super easy to work with and immediately sent me replacements. I have now put Lasfit in all my vehicles.

Leave for work in the dark and get home in the dark. These are a big upgrade for me. I’m happy with them

I highly recommend Lasfit. I Purchased H4 9003 LED bulbs and H11 LED Switchback fog light bulbs and they are by far better than any other LED bulbs I have ever purchased. Clean, crisp bright white light. Plug and play. Absolutely worth the money, you won’t be disappointed.

I love these lights so much they give my ride a great look and the light output is insane over stock halogen bulbs thank you LASFIT!!

I was surprised with how bright these were ! I’ve ran multiple led bulbs from different brands and they all were cheap and had a weird beam pattern, as soon as I installed these LA Super Series it was a night and day difference they’re so bright and have a nice cutoff so I don’t blind oncoming drivers !! So far 10/10 highly recommended

Purchased my bike last month and it came with factory halogen lights. Haven't driven a vehicle with basic halogens in a long time so keeping these was a no go. Did not want to get into a lengthy headlamp conversion during riding season that would possibly keep the bike down for weeks and did not want to deal with trying to hide any sort of ballast or control boxes therefore I decided on the LA plus LED H4's as it was a good plug and play option for the bike. I especially liked the fact that the mounting frame was removable from the bulb making install a dream as I did not have to trim the factory rubber boot on the back of the light assemblies. The light output is great even though the housings are basic reflector style and the look and color is awesome. I also went with blue LED 194 Lasfit bulbs for the parking lights which are inside the headlight housings. the H4's plus the blue small bulbs mixing together give off a really nice effect. I will keep these going until I decide to do some sort of full headlight conversion for better more directed light output. Thanks Lasfit!

Great upgrade for my cruiser. I live in the mountains of central Colorado and frequently drive in adverse conditions. The Lasfit bulbs really increase my confidence in seeing the next deer or elk in my path.

Having the same as another person that purchased this product. Very impressed with how bright these lights actually are, regular low beams make everything look like day, yet the high beams have a huge dark spot making them completely useless, and outright dangerous trying to even use them at night..

I made sure to contact support and they made sure I had them aimed correctly, and still no difference whatsoever.

The low beams seem to blind everyone, creating a huge ball of light, only convenient to the owner, while blinding everyone else. Now the high beams do seem to spread the light, but again, the huge dark circle makes them outright unusable, making the view of the road completely dark.

I've tried turning them all different ways, pushing as far in as possible, and moving them out, and no difference.

This might just be my own issue as the reflector housings on the car have big caps in front of the bulbs that force the light sideways onto the reflector, thus stopping all light from traveling directly straight? Which makes no sense as the low beams are 5x brighter.

Great product, but my use case had major flaws.
