I bought these 6000K bulbs to replace the original low beam bulbs on my 2004 Lexus LS430. Original ones were nearing their life and going off intermittently while driving. These bulbs provide bright white light. Easy installation, prefect fit, right out of the box. No flickering, no issues. Good experience so far.

Je pensait que la luminosité aurait été plus forte

Justamente lo que buscaba, es indistinguible la diferencia en los tonos de la Luz. Excelente opción.

After 3 days, 1 bulb started to flicker between white and blue. Had to remove and replace with Sylvania bulb. 4 more days pass, the other bulb just dies. Don't waste your time and money folks.

Se cambian bien facil y alumbran muchisimo. Lo recomiendo.

Excellentes ampoules de remplacement. L'empaquetage est super et la livraison rapicde.

Beamtech does it again. I've gone through a ton of different LED bulbs over the last couple years and Beamtech consistently delivers a great bulb for a low price. These things are insanely bright. I have a 2017 Honda Pioneer 1000 EPS that I use for work, and if you've ever driven one at night, you know the stock headlights are freaking garbage. The most common remedy is to just bolt a light bar onto your rig and call it a day...but since my Pioneer is a work-owned machine, I can't do that. These bulbs are an absolute must-have whether you are in a similar situation or not, because they are easily twice as bright. The bases are fully adjustable, so you can get them oriented perfectly to side-fire into the reflector (which is how they are supposed to be oriented). This is a fanless design so no humming or moving parts to get gunked up and break, plus they fit right up into the housing and allow you to re-use the factory hard plastic dust cap that snaps onto the back to keep mud/debris out.I've included pictures of the stock bulbs vs the Beamtech H13's. I tried to stop in roughly the same place on my road so you get an accurate perspective of just how much brighter these bulbs are (look at the ditches and the power pole to the right for a comparison). The pics were taken at night with a Galaxy Note 10 Plus, with the headlights on low-beam and the camera set to manual mode. This means that the images are NOT auto corrected for brightness by the camera software. This is actual output captured by the camera with the same settings for each bulb type, so no post-editing trickery to make the LED's look brighter (ISO 200, f/stop 1.5, and shutter speed 1/30 for both shots).The only thing out of my control was the snow we just got, which may be scattering the light ever so slightly...but it's unlikely that it's making a huge difference in the photo. I will post an update with an additional night shot once the snow melts off. It looks impressive in the photos, but in person the difference is pretty stunning.Officially the best $40 I've ever spent on this machine. Buy them, you won't be disappointed.Note: I bought these bulbs myself. I'm not sponsored by Beamtech nor am I a company shill. I'm a legit end user who works on a cattle ranch in Nevada in the middle of nowhere. Out here, lights = safety, and these things deliver.

I was looking for new headlight bulbs to match my vehicle's daytime running LED's. Originally I thought about going with 6500k+ halogen bulbs, but upon finding these Beamtech H13's I decided to give these LED bulbs a try. Most reviews on LED bulbs mention that LED's in a Halogen housing tend to have bad light distribution, or improper angles, so I was reluctant at first. Now that I have them, I wouldn't have chosen any other bulb.Pros: Perfect fitment, great light distribution both low beams and high beams, instant illumination when switched on, color directly matches my daytime running LED's, easy installation, and most likely longer life span than stock/premium halogen bulbs. These bulbs provide a brilliant white light with a slightly bluish tint, which is common in modern HID and Xenon lights.Cons: You will need to locate a good place to fit the wiring after installation. The wire itself is only about 2 inches long so it shouldn't be much of a hassle. These bulbs will also require you to calibrate them to your specific vehicle's headlight housing. This takes only a few minutes and will ensure proper light distribution and aim. These bulbs are also a bit longer than a normal halogen bulb due to there being a heatsink on the bulb itself, so be sure to give the heatsink room for fitment and to move any objects such as wires or plastic away from it to protect against unwanted damages.If you are getting improper light distribution or bad aim, be sure to try these steps first before returning this product:There is a picture in the instructions booklet included with these bulbs telling you which LED's are for the high beams and which are for the low beams. Keep this in mind during installation.There is a small screw linking the bulb to the harness which holds the bulb in place. Remove this screw with the provided allen wrench so the bulb can be turned in it's harness (KEEP AN EYE ON THIS SCREW AFTER REMOVAL. It is very small and can easily be lost if you are not careful). Once you remove the screw, install the bulb as normal, plug it in and turn your headlights on. Once you have the bulbs in the housing and turned on, slowly turn the bulb in it's harness to aim the LED's. It may take a few minutes to get them properly aligned, but you will want to make sure it's perfectly aligned so you get good illumination of the road at night and so you don't blind others on the road. Test the high beams while performing this calibration to ensure that it is properly aligned. The high beams should provide illumination ABOVE the low beams. Once you have aligned the bulb, memorize where the Beamtech Logo is on the heatsink so you can remember where it is supposed to be during the next step, some vehicles have little space to install bulbs so it may be difficult to remove these LED bulbs after calibration without moving the bulb within it's harness. After calibration, unhook the wire and unlock the harness, keeping in mind where the logo is after unlocking the harness from the vehicle, then remove the bulbs from the vehicle. With the bulbs now aimed, replace the small screw with the bulb in it's new position within the harness, now locking the bulb in place. Then reinstall the bulb into the vehicle, plug it in and re-test the bulb. It should now be aimed properly. If not, repeat these steps to ensure they are properly aimed.If you have any other issues with these bulbs, such as flickering or the bulb going out in less than 1 year, contact the seller using the "Ask Seller" button in your Amazon Orders page.
