Well, so far so good. I’ll definitely update my review as time goes on but I’m currently very happy with these! I drive a 2023 Hyundai Kona SE (facelift model), I mention the facelift because it does have different style bulbs so I can’t guarantee the same results in earlier models. I hated the dim and ugly looking halogen bulbs that came OEM and had originally swapped them with Lasfit bulbs that were even worse than OEM… They even cut the light pattern and made completely dark spots, so they had to go… I found these and thought the design was very unique and that it would resolve the dark spot issue with the Lasfit bulbs, and I was right! Oh, and these are less expensive too… Some people complained about the pigtails on these lights, but for my Kona they worked out perfectly! This model Kona has stupid short connections, you have to put the bulbs in and then connect them, P.I.A… The pigtails on these allowed me to connect them first and not have to strain to get them connected afterwards. They tuck away in the dust cap very nicely. Once everything was installed and capped back up I couldn’t believe the beautifully wide and bright light they emitted! Took a quick ride around once it got nice and dark to test them out, I had a smile ear to ear! If your looking for an awesomely bright upgrade I, as of right now, highly recommend these bulbs! If this review is the same in a few months then I still love them!

I put these in my '13 Dodge Ram truck. They give a pure white beam which really helps me to see at night over the stock halogen bulbs. These were easy to install, just like the stock bulbs, and I'm impressed with how much better I can see forward and off to the sides and my early morning (pre-sunrise) commute is much better now.The build quality is great with a machined aluminum body with heat sinks built in, and the internal cooling fan will keep them from getting too hot.I've had them in my truck for about a month now with no issues, so only time will tell as far as the durability/longevity of these bulbs, but I'm confident that they will last.If you have older halogen bulbs and are looking for an upgrade, I definitely recommend these.

I've tried a lot of different lights in my car and these are the second best of the seven I've tried. I'm kind of a headlight hypochondriac because I have dubious night vision. Halogen bulbs I kept checking to make sure they were still on. They have a good spread and defined line so i know I'm notblinding oncoming traffic, which is nice because I only like to blind people if they deserve it, and I have high beams for that. These are definitely worth it.

Bright, quiet, will update on output over night. PS: always install LED bulbs with emiters parallel to reflector grooves if you dont have projector headlights.Update: Ran it, lights are proper bright, remember to realign your headlight assembly to proper levels.

I highly recommend anything from Marsauto. This the fourth set of LEDs I've used from Marsauto and they all worked great.

Much better than most other LED replacement lamps.

I've tried a few different LED bulbs in my round motorcycle headlight - none of them preformed to my liking until I tried these. Many times when you put a LED bulb in a halogen light housing the beam pattern is terrible and is blinding to on-coming traffic. These bulb are the closest I have found that produce close to the same beam pattern as the halogen bulb did - actually they produce a nicer beam than the halogen as the cut off is very defined now - plus they are adjustable. If you're looking for a LED replacement for a 7" round headlight I recommend given these a go. I'm sure they would work great in a car/truck as well but I only tested them for my motorcycle headlight. Comes nicely packed with instructions, gloves, and 2 bulbs.Bench Testing: (Testing a single bulb)I ran the bulb on the bench for 2-hour straight so I could record the voltage, amperage & heat data.Voltage Supplied: 13.7vdcAmperage Draw: 2.6ampsHeat Ranges:• Tested Without & with headlight being installed in headlight bucket.• Recorded 4 different areas of the bulb and headlightBulb installed in headlamp housing but not in bucket: (1-hour)Heat Sink 160FHeadlight Housing 92FBack of Bulb at retainer 170FFront of headlight lens 97FBulb installed in headlamp and in headlamp mounting bucket. With 4" fan blowing 6.7mph onto front of lens (1-hour). Since there is a small space around the headlamp bezel and the headlight when its mounted in the bucket I thought the fan would help simulate how a small airflow would affect the heat range when riding.Heat Sink 125FHeadlight Housing 79FBack of Bulb at retainer 136FFront of headlight lens 75FThe temps showed that it would be fine to mount to the motorcycle so after a quick adjustment of the bulb which you do by simply rotating the bulb within the retainer ring I set out to test the on-the-road light output. The light and beam pattern is so much better than the other bulbs I have used in the past and I didn't get people flashing their lights at me which tells me it's no longer blinding oncoming traffic.

I would love to use these in my truck, but...Flat LED bulbs are best suited for projector-style headlights and my truck has standard "reflector" headlights.The bulbs themselves don't have the proper cutoff built in (like OEM halogen bulbs do), so the light at the top of the headlight just scatters. It creates a wide, uncontrolled beam that can be blinding to oncoming drivers.They do a great job of lighting up what's in front of you, but I don't like seeing them in oncoming cars at night because of the glare.But, when you put them in projector headlights, they look great. And that's what the style is designed for.I'll use these in my off road vehicles, but not on public roads (out of respect for other drivers).This does, however, make me want to get projector headlights for my truck...
