I recently upgraded my car's headlights with the ROYLUX H4 LED Headlight Bulb, and I must say, I am thoroughly impressed with its performance. This LED conversion kit is a game-changer, offering an unparalleled level of brightness and clarity that far surpasses traditional halogen or HID bulbs.The first thing that caught my attention was the astonishing brightness of these bulbs. With an impressive 120W power output and 24000LM output, they provide a staggering 600% increase in brightness compared to standard halogen bulbs. On the road, the difference is truly night and day, illuminating the surroundings with a crisp, white 6000K color temperature that greatly enhances visibility during nighttime driving. The Hi/Lo beam feature works flawlessly, allowing me to switch between the two modes effortlessly.What really sets the ROYLUX H4 LED bulbs apart is their easy installation process. The "plug and play" design makes it a breeze to install them into the existing headlight socket without the need for any modifications or complicated wiring. Within minutes, I had both bulbs securely in place, and they fit perfectly, ensuring proper alignment for optimal beam patterns.Additionally, the build quality of these bulbs is exceptional. They feel sturdy and well-made, assuring me of their durability and longevity. The efficient heat dissipation mechanism prevents overheating, making them reliable even during prolonged usage.The most significant advantage of these LED bulbs is the cost-saving aspect. While the initial investment might seem higher than traditional halogen bulbs, the reduced power consumption and extended lifespan of the ROYLUX H4 LEDs more than make up for it in the long run. I can rest easy knowing that I won't have to replace them frequently, which is both environmentally friendly and economically beneficial.In conclusion, the ROYLUX H4 LED Headlight Bulb is a top-notch product that exceeds expectations in every aspect. Its remarkable brightness, ease of installation, and energy efficiency make it a worthwhile investment for anyone seeking a safer and more enjoyable driving experience. If you're looking to upgrade your headlights, I highly recommend giving these LED bulbs a try – you won't be disappointed.

I love these bulbs! I'm always looking for the next best thing and these are it. I've tried other LED bulbs and none were any better than stock. I'm using these on a 2001 Honda VFR800 and they give me probably double the range of my current halogen bulbs. I did have to lower the up/down slightly to not blind oncoming drivers. I wanted to use these on my car also, but there wasn't enough space behind the bulbs. Don't know how long they will last but we will find out!

Lo primero que se nota es que son materiales de calidad...la luz blanca led es espectacular me di cuenta que la luz que tenia antes era muy,muy deficiente.Esperemos que sean durables como aparenta ser.

I don't do a lot of reviews, but owners of Toyota Tundras need some good info, because there's not much out there. Since you're here looking at LED lights, you're probably just like me and sick of your weak yellow headlights barely lighting the road, and you're wondering if LED bulbs will fix it. The answer is... Yes, but you need to add resisters as well. Regular halogen bulbs use much more electricity than LEDs, so when you plug in your New LED bulbs, the abundance of electricity returning to the Tundras computer makes it think the bulb is not working. I added these resisters from Amazon https://www.amazon.com/dp/B07SGCHF5B?psc=1&ref=ppx_yo2ov_dt_b_product_details (Xprite LED Headlight Canbus Anti-Flicker Harness). You simply plug one into each headlight and then I just used a wire to secure them to the frame above the headlight (see pics). Without a resister, the fog lights will not work. In fact, with LED bulbs in the headlights, your fog light switch actually suddenly controls your High/low beams function instead. Crazy, huh? I tried using only one resister and the fog lights did work, but the headlight without a resister began to flicker. The good news is that using two resisters fixed all of that. Now I have SUPER BRIGHT LED headlights (These lightbulbs work!) and I have LED fog Lights as well and they all work like they are supposed to. Do the same setup on your truck and you will finally be able to see the road at night. Good Luck!

Easy install, super bright and most importantly it doesn't need an adapter for DRL. Previously purchased a Fahren LED headlamp and it was triggering the DRL alarm randomly which was really frustrating but this one worked great without any DRL alarm.

Nice and quite fan, very bright and good build quality. I can’t recommend these enough

It ok

2016 Toyota Tundra. I wanted to change out my old dull halogen bulbs for LED's, but wasn't sure it would work well. I've been reading many LED bulb reviews over the last couple of years and wasn't very impressed. Then I read about these and ordered them. They fit perfectly without having to modify anything - just change them out like any other bulb. Wow! What a difference. No cut off lines on the beams, just pure white light lighting up the entire road. Make sure you adjust the aim down if needed to prevent blinding oncoming vehicles. Highly recommend. You will be 100% satisfied.
