Trueland H4 9003 LED Headlight Bulb with Canbus Decoder 10000LM Super Bright 6000K H4 High Low Beam Anti Flickering Coversion Kit Pack of 2

TrueLand, I must say I’m sold on these bulbs.They are super bright and illuminate the street better than I thought.Thanks so much, you have brighten my life with these LED bulbs.Check out my pictures they are awesome…

These were very easy to install. You just install the base ring and snap it in place with the wire clip that held the old bulb in place. Then you insert the new bulb into the base ring and twist to lock it in place. The first thing I noticed about these bulbs was that the low beams lit up the road much farther out. At first, I was worried that they might be too bright for oncoming traffic, but I have never had anyone flash their brights at me thinking my lights were on high beam or too bright. In fact, you can see the upper quadrants go quite dark when you drop the high beams, yet the road itself remains very well lit. I also like it that they are a white light and not the bluish cast. These bulbs come well packaged and appear to be of quality construction. I have been very pleased with this purchase.

The media could not be loaded.  Installed on a 2017 VW Beetle. Nice fit but flickers when turned on even with the built-in Canbus Decoder which is suppose to prevent flickering. Seller offered to send me a "stronger" decoder but will arrive in around 20 days from China. That would pass my return window with Amazon so it is being returned. Plus another device in the chain is not a good thing.

Ordered these to replace an old HID conversion that is no longer available . Upon installing I lost high beam and fog light capabilities. The high beam indicator on the dash no longer worked. These only had on/off, not sure if it was high or low but it was very bright. Installed some new halogen bulbs from the parts store, and everything works fine again.

Super bright LED in bright white with no hint of blue. Has wide field of view and no dark spots. Had fitment issue and customer was quick to respond. Hit up Rose and she answers you within 5 mins. Did not hear the fans from lights. Super silent operation.*update* owned since October 2018. Initially had problem fitting H4 into Mercedes 190E euro headlight. Contacted their customer service and they wanted me to keep the review 5 stars but only if I posted that, then they would refund me via Paypal. Of course I did not get a full refund on Paypal since they charge for currency conversion. Installed in a 1992 Mercedes S class and they fight. It was too tight to fit into the socket in the 190E. Weird issue.Anyways the bulbs were bright but now 8 months later they give the computer a burned out bulb signal when I use the high beams. It also causes the needles to jump on speedometer for some reason. Emailed the seller but they ignored me on June 7, 2019. My other Mercedes cars used Sealight led brand and have had zero issues with computer problems. Buyer beware!

I purchased many other LED bulbs but these did the job. The canbus that was included into the harness preventing the flickering of the LED bulbs. These are some of the brightest and cleanest looking LED bulbs I have purchased. The picture doesn’t do it justice but they are a bright white and far superior than my stock e these are some of the brightest and cleanest looking LED bulbs I have purchased. The picture doesn’t do it justice but they are a bright white and far superior than my stock headlight bulbs. They work great within my projection housing and I do not get an odd pattern. I highly recommend these for anybody looking to upgrade their Headlight bulbs.

I have a 3rd gen Toyota 4-Runner. I have to manually turn off my fog lights before I can use high beams. Also I can't turn off the lights. This is because the 4-Runner trys to run the lights in "daylight mode". To do this it pulses the lights on and off very quickly. With incandescent bulbs the effect is to dim the lights, but with these it just causes them to flicker. Finally the 5000K color may look brighter when you see the car, but doesn't necessarily make the road brighter. It really feels like you are driving with moonlight. Now, when I have low beams on and someone flashes their brights at me I can't flash my brights back. The effect is that rather than going to high beam, my fog lights just turn off. Now with low beam AND my fog lights on its not so bad since my fog lights add a small amount of yellow color which makes for a more natural view.

These are great for what they are. Have lasted well so far. They’re a bit cheaper than the Opt-7’s. They are not as bright, but have better pattern disbursement. They cast down a bit more, but not enough to bother me. These are a good choice for a cheap switch to led. My Opt-7’s lasted 3 years. These have lasted 1 so far. We will see. I will update when at least one of these goes out on me.Update: 4/17/21: these are still working fine so far.
