Review on 💡 LASFIT H4 9003 HB2 LED Bulbs, 6000K Cool White Hi/Lo Adjustable Beam Conversion Kit, Plug and Play (2pcs) by Carlos Burrows

They're bright, there's no denying that, but there are some issues. The beam spread with a standard housing is extremely large. Get ready for constant blinking, unless you tilt them down, which somewhat cancels out their brightness. The color temperature leaves a lot to be desired. They are in the range of 7-8k, despite what the description claims, IMHO you lose a lot of clarity. Installation can be a real pain depending on the type of system your vehicle uses to mount the bulb. The collars on my Suzuki (also similar to the Ford style) are a bit annoying because they have to be properly aligned. The spring clamps my Honda CRV uses are a huge headache due to the size of these bulbs. A 2 minute job turned into a 30 minute hassle. They are not sealed. The fact that they use built-in fans encourages moisture to enter the case. If you ride off-road like me and are deep enough to submerge your headlights in water for any length of time, you will literally fill the lenses with water. However, for me they have been extremely durable and reliable, even after diving. Your mileage may vary.
