Installed these last night on a 2014 Taurus with projector headlamps. The install was pretty easy but I couldn't find anywhere to mount the ballast. Also the double sided sticky tape doesn't stay on the metal ballast. The Taurus has a rubber grommet covering the bulb housing so you can mount the ballast outside the housing because the rubber cover won't stay on with wires coming out. So I just stuffed the ballast and wiring into the housing away from the back of the bulb and out the rubber cover on. Hopefully it works ok and doesn't get too hot.

The bulbs have an adjuster so you can get the bulb to 3 o'clock and 9 o'clock which is ideal for LED bulbs. You have to use the Alan wrench that comes with it to adjust and it takes some trial and error. Also when you plug the light in make sure the light turns on and if it doesn't flip it over and replug it back in. It only works one way.

Check out my pics. One of them is with the old Silverstar on the left and new LED on the right. The other pics are all the new LEDs with low and high beams. Hopefully these last a year or more.

I've only had the Fahren H4/HB2/9003 LED bulbs installed in my 2000 Honda Civic LX for a about one week. I previously had Philips Crystal Ultra Bright halogen bulbs installed, that I also liked. Very bright and great color.

Here are a few observations so far:

It appears that the Fahren LED bulbs might be brighter yet than the Philips halogens. Interestingly to me, with both bulbs (Philips & Fahren) I never need to engage high beams to illuminate highway signs at night. The low beams are plenty bright enough for that. With both bulbs. Could be the way my headlights are adjusted, but it works well.

The Philips high beams appear to have been angled differently than these Fahrens. I never thought to adjust them, as they seemed well collimated. But when I engaged the high beams on the Philips, it made highway signs glare. I didn't think to adjust the Philips, but I think it is possible. And sometimes oncoming drivers would flash their high beams when I drove with my Philips high beams engaged, which I often did to improve nighttime vision. Especially in the rain.

Which brings up the potential issue of hazing on 20-yr.-old polycarbonate headlight lenses, and that factor influencing collimation and ideal road illumination. I liked the Philips, but felt they were deficient in the rain at night. Moisture in the air both reflects and refracts light, diminishing collimation of headlight beams and illumination, vision.

I think the Fahrens are better in this circumstance. And here's another reason why:

While the low-beam setting is actually a pretty sufficient combined low/high beam pattern, the high-beam setting actually appears to increase the near-field (low-beam) illumination of the immediate near-field road. And beyond, for a decent distance. I think this helps very much to increase visibility and security at night. And even with both low- and high-beams on it appears they do not blind oncoming drivers at night. Quite a good thing. They appear to be well collimated in this way, and I appreciate the ability to use both beams as I need to.

The real issue for me is night driving in the rain. I liked the Philips Ultra Crystal halogens, but they left me without adequate vision at night in the rain. Perhaps an adjustment would have helped. I think the Fahrens LEDs are better. In large part because of that useful high-beam setting. In good weather, they are very good.

Which leads me to consider new headlight lenses to achieve maximum benefit. My lenses have been sanded and buffed at least once 3 years ago, the car in very good shape for its age. So the lenses are not terribly hazed, but there is definitely some. Likely new lenses would improve any bulbs, but they might make the Fahrens even better.

The other consideration is 'adjustment' of the bulbs' collimation. Another great thing about the Fahrens is the ease of adjustment by the circular ring around the outside of the bulb housing. Very easy to adjust. And I haven't tried that yet, but think I will to experiment with the illumination pattern.

I think the Philips might have benefited from such adjustment also. Though, except for performance in the rain, I thought they were fine bulbs. Lasted me just shy of 3 years when the driver's side low-beam went out. Could still drive with high-beam engaged, and didn't seem to bother most oncoming drivers.

I am keeping the Fahrens. Because they are bright, clear, well-collimated and can be used with both low- and high-beams on, if needed. And I like that addit'l near-field illumination. I can't say if the pattern will be exactly the same on your auto, but on a 2000 Honda Civic LX they likely will be. And, unlike one purchaser, who apparently needed a CanBUS added to make the bulbs work on his 2000 Honda Civic LX, I didn't require this. The bulbs work just fine and have from the start. Which leads me to think something in his electrical system is not exactly right. Weak alternator/regulator? Something in the wiring changed?

In conclusion, after a lengthy report, I should add that, after registering my new Fahren LED bulbs with customer service I was, as promised, provided an Addit'l One Year Warranty, making it a 2-Year Warranty now. Pretty good, I'd say.

I had a lot of questions for customer service before installing these bulbs and I have to say that they were always prompt in responding. And helpful in answering. It's always a pleasant experience to encounter Good Customer Service. We all know what the opposite is like. I believe this is a quality product. It's great that Customer Service appears to be of similar quality. They even offered me a 99% Discount on the CanBUS if I needed it. Very generous of them. Glad I didn't need it

I'll try to report back if I have further observations to make. In the meantime, I might see about adjusting the bulbs (easy, as previously described). And see about New Headlight Lenses.

The troubling issue with Replacement Lenses is the problem with headlight collimation 'adjusters' that appear to be present in photos of part, but end up not working upon installation. And if they are not aligned, the new lenses are useless. That, or other issues. Though some people have had good luck.

These are good, bright LED bulbs. And the installation for me was very easy. Great that they are easily adjustable, too. And if you decide you don't want to keep them, you have a generous 30-day window to return them. Pretty good deal. And so far, I like these bulbs very much. I'll like them even more if they last 50K hours. Then, they'll be extremely cost effective.

*Update: I did in fact need a CanBUS unit, but Fahren's unit did NOT work at all. Get the alternative for a little more money, which Fahren will help defray cost of to make headlight bulbs work.

I needed the CanBUS unit in order to get the high-beams to work. Only the low-beams worked without the CanBUS. Definitely worth the cost of the CanBUS to get the high-beams to work. And easy to install the CanBUS.

I won't speak on longevity, as I just finished installing. But:
2007 Camry with OE headlamps and fog lights

I with new headlamps on the way, I know that a lot of my poor lighting is due to the originals I currently have. Although I've taken good care and have restored them a couple times. I noticed an immediate difference between these bulbs and the silverstars I had in previously. The wider view is great. I can see curb to curb easily and I no longer am drowned out by other vehicles lights beside me, nor when incoming traffic is super bright.

I also tried the "Lasfit" brand LEDs and those get very hot very quickly and were dim. I ordered some "Sealights" as well but after seeing these work and the small form factor, along with a very reasonably quiet fan assy that I can only hear when the car is completely off and lights still on (4 total bulbs) I am going to keep theseand return the rest.

I also have little concern that these will melt/heat up the housing on the headlamps as they weren't very hot after being on.

Street signs showed more reflection, but noticed a solid line on cars ahead of me at stop lights so I assume these aren't blinding those in front of me. I'll adjust my headlamps if necessary once the new ones arrive and I replace them. But as of right now these are a plug and play easy install bulb that fits OE headlamps.

This review is written by my husband:

These are very bright! I am very impressed! WELL worth the money! These are well made and the fans are fairly quiet. (They're still fans.)

Here's the Long story: I have a 2014 GMC Sierra. I tried another brand of LED (not sure what brand) in this pickup because the stock ones were horrible and I had a very hard time seeing the road with them. Those other LEDs were okay, but still were not much brighter than stock. I figured that maybe the housings were not letting the light out or something, so I just decided to leave them alone.

I bought these 9012 LED lights for my wife's vehicle and they worked very well! After a short time, my wife decided she was trading her vehicle in. I took these lights back out and put her stock ones back in. Her new vehicle had LEDs, so I didn't need to use these LEDs. After a couple months I ran across these lights in the garage. I decided to see if these lights were any better than the ones I had in the GMC Sierra pickup. I put one light in the GMC Sierra and turned them on. WOW! You wouldn't believe the difference! The other LED that I hadn't changed out was drowned out by the one I just put in!! These also have a set screw for adjustment and the little wrench came with the set! I adjusted both lights, put them in, then put everything back together. I fired up my pickup and drove down the road a little bit and I could actually see the road in front of me better than I ever have been able to in this pickup!! I would most definitely recommend these and I would definitely buy these again!
Thank you for reading.

Very bright with a cold temperature light. I just replaced a pair Philips 9003 VisionPlus halogen bulbs with these Fahren H4/9003/HB2 LED Bulbs. For the original halogen headlights, the low beams drew about 4.2 amps and high beams 4.9 amps per bulb. At 13 volts (Power = Voltage x Current), that's 54.6 watts and 63.7 watts. These LED replacements only draw 2.2 amps for the low beam and 2.3 amps for the high beams, which is about half of the halogens. The LED have a cooler color temperature, are noticeably brighter than the halogen bulbs, but were much more difficult to install on my 2008 Toyota Tacoma. I am also surprised that the high beams consume hardly any more current than the low beams. I guess the term high beam refers to the fact that the light is projected higher in the air.

For the installation, I attached the rubber boot to the LED light assembly before installing them in the headlight assembly. The passenger side took about seventeen attempts before I was able to secure the locking clip in its slot. I also had to remove the bolts from the windshield wiper reservoir to get more room. The driver side went in on the first attempt. For a first time installation, these literally took about ten times longer to install than the old halogens.
