H4(9003) 6000K 8000 Lumens Led Headlight Bulb Conversion Kit,Leakind 80W Plug and Play Crystal Clear Cool White Bulbs, 3 Year Warranty

These lights are brighter than the OEM headlights that came with my 2015 Toyota Tacoma. The rubber seal that covers the back side of the headlight assembly did not fit with these installed. It does not seem to cause any problems, but it makes me a little nervous.Pros:Bright, white light for great visibilityCons:High Beam makes very little to no difference!! In other words, the high beams are useless!!The rubber seal that covers the back side of the headlight assembly did not fit with these installed.The light seems diffused to the extent that I am frequently being flashed as they shine into the eyes of on-coming drivers.

These lights work pretty good, but I got the 9003s which have both high and low beams in the same bulb. When turning on the high beams, you can see that more LEDs turn on, but light output is exactly the same. What I've done is added a resistor to the low beam power signal on each light which reduces the light output on the low, thus making the high beams more noticeable when they come on. The reason I did this was because the Safety Inspection officer needed to see a distinguishable light output between high and low beams when my registration came up for renewal.

The H3(9003) 6000k 8000 Lumen bulbs are indeed bright. At the stated 4000 lumens each they produce a night bright white light. The projection is good with a minor exception. For our Subaru Forester there appears to be a V shaped pattern to the projection which leaves a dark spot. Additionally the way the bulbs are held in place on the Forester by a spring clamp, the base of the heatsink is in the way and the clamp had to be bent to allow the clamp to seat in and hold the bulb. Also the rubber boot seal doesn't fit due to the heatsink. Will have to see if any water makes its way into the light housing over time.As others have noted the light output on high beam mode is not greater. From what I can see on my set up is that the high beam is actually not as bright as the low beam, it only throws the light at a higher projection to illuminate potentially farther down the road. This leads to the question I have about the stated lumen rating. The older set of LED bulbs I am replacing had a rating of 3000 lumens and in comparing the 2 they appear to be the same brightness.Overall the bulbs are OK, time will tell...

they are bright !! dark spots on each headlight, very little difference between low & high beams ! people keep flashing me i have them aimed as low as I can. I live in Montana where it's darker than black at night. On nov 29 2017 I had one light quit working ,about 5 minutes later the other light went really DIM. had to call my wife to come an get me so I could follow her home since I had very little light from the one dim light. they supposably have a 3 year warranty , I do not want any more headlights I would like just to get my money back !! send me a return shipper labile , or I can throw them in the trash can!! Buy the way the lights quit working 2 days after the 30 day return was up. Also I bought a set of led's from Grandview an they work great! I'll let you know if I get my money back.

So I bought these headlights as my first set of LED's. I'm an automotive mechanic and know there are a hundred options to buy. I must say the ease of install is incredible. They took 10 minutes and I was installing them on a Yamaha YZF-R1. I was riding the other day and was almost ran off the road during the day! So I figured let's upgrade the lights to make myself more visible. But little did I know how much they would improve my night time riding. For the money, your not gonna beat these headlights. Do yourself a favor and buy a set for your car. They will significantly improve your night time driving.

Not a true H4 replacement bulb. There is no deference from normal lights to brights. A true H4 light has a top part that is low beam light, and the bottom is high beam. The leds on these lights are on the side, so you can be pulled over have your brights on even when they are not, because light from the leds are illuminating the portion of the light that is reserved for high beams.

Huge improvement over stock headlights. Only negative is the high beams are barely noticeable, but not a problem because lows are so bright you don't need high beams.. Driven aprox. 1000 miles and about 5 cars have flashed me for highbeams. It's crazy how well they light up all street signs ahead even ones very very far away. They were very easy to install. I hope they last many years. Highly recommendedUPDATE: right light stopped working today. lasted almost exactly 1 year. Not that great. i don't know if they will warranty it? i should take away one star. WILL UPDATE IF THEY REPLACE FOR FREE..

PROS:*Nice headlight bulbs appear to be well built*Fairly bright mostly bluish white light*Reminded me of Mass Effect with the N7*Installed in 2009 Honda Element under an 45mins*Perfect fit*Taking old bulbs out was a breezeCONS:*Clip that holds bulbs in place on Element gave me a little trouble when trying to lock new bulbs in place*After installing these bulbs I could not reinstall my oem dust covers/caps*I should have bought electrical tape to tape around the plug and socket it seems a little to exposed to my liking*I should have bought a 3m headlight or similar restorer*High beam is a tad bit brighter but not by much*No warranty info on or in box*Will update if I have issues
