Perfect upgrade for a 1999 F150!
Anyone with an older vehicle knows what halogen lights are like. At night in a dark road you are lucky not overdriving them at 45mph. These LED bulbs are a seriously better upgrade for the same price as the average halogen available now with such a brighter lighting capability. They fit is exactly the same as the older ones, and really improved the quality if light at night and increased visibility to a much safer level. They even look much nicer than the halogen bulbs and the internal cooling fan keeps them from overheating. They are 100% compatible with our 99 F150, and only took a few minutes to swap out. There is a noticeable noise when they turn on from the cooling fan, but it is only really heard if you are actually standing by the front of the truck. I don't know how long they will last, but if they last even as long as a standard bulb, they are definitely worth trying. There isn't a price on safety, and my family is much safer with these bulbs instead of the stock equipment. 100% recommended and very happy to have better night vision!

Really bright and perfect for night drives
Wow very nice bright lights that installed with no problem on my car. The fit was perfect and no extra tools needed just take off the old bulb and put the new one on. So far they have no given me any issues and the color is really bright which helps me see at night. My other bulbs do not compare this is way better. All i had to do was twist and pull the other bulb out and install this one which was easy.

Great Replacement LED Headlight Bulbs - Super Bright & Clear and Really Improves Driving Safety
I am very impressed by these LED headlight replacement bulbs - they are very bright (but not blindingly bright to the point that other drivers are flashing their lights at you) and the white temperature is perfect color accuracy for very clear & clean driving which greatly increases safety on the road. The replacement headlight bulbs were very easy to install by simply removing the old bulbs, plugging these into the wiring harness and then inserting them back into the headlight housing...although I will admit that one side of my vehicle was harder to get to because the vehicle battery was in the way, but that had nothing to do with the bulb and I eventually was able to maneuver the bulb into place so just be aware of this and I'll note by saying that this would have been an issue with ANY bulbs because of the tight space behind the headlight housing of the vehicle. Would definitely recommend and because of my high level of satisfaction these are definitely 5 star and a good value for your money.

Solid lights
Not bad for the price I bought for my 1990 Nissan z32 keep in mind there nothing top of the line but compared to halogen there definitely a upgrade they had a tight fit into the headlight assembly which is good there pretty bright and easy to install it’s a smaller design compared to others so helped with a tighter area to work with

Awesome Sauce!
YES!!! These are the perfect headlights. Plug and play in my 2018 Hyundai Sonata Sport. Will be buying a new set for the high beams. Instant clarity, better visibility, and just crispy all around! You can see the difference in the two from the photos below. I replaced on so you can see the difference, then replaced the other to see the evenness. It is a little dark close to the car, but my concern was being able to see clearer farther. Will return after I buy the next set for the high beams!

Perfect, absolutely worth it
Great headlights, super easy to install, really bright, all and all simply perfect. I honestly never leave reviews for things but I felt I had to make an exception with these as the bulbs genuinely exceeded my expectations by far. I honestly dont think there's anyway you could wrong with purchasing these (unless you select the wrong type of bulb for your car)

Good Light Production
Nice and bright. They fit nice in the compartment. The only thing I would say is that a couple were loosely put together with a little rattle(production issue I would suppose). I have only had them in for a couple weeks, but for the price I would recommend.
