Purchasing H4 LED Bulbs
Compatibility:
Vehicle Model: Ensure the H4 LED bulbs are compatible with your vehicle. Check the owner's manual or consult the manufacturer.
Socket Type: Verify that your vehicle uses H4 (9003) bulbs, which are dual-beam bulbs (high and low beam in one bulb).
Brightness and Color Temperature:
Lumens: Look for bulbs with a higher lumen count for better brightness. Typically, 6000-8000 lumens per pair is adequate.
Color Temperature: A color temperature of 6000K (bright white) is common and provides good visibility without being too blue.
Quality and Durability:
Brand: Opt for reputable brands like Novsight for quality assurance.
Heat Dissipation: Choose bulbs with good heat dissipation features, such as built-in fans or aluminum housings, to prevent overheating.
Lifespan: Look for bulbs with a longer lifespan, typically rated around 30,000-50,000 hours.
Beam Pattern:
Ensure the bulbs provide a focused beam pattern to avoid glare for oncoming traffic. Look for bulbs with a clear cut-off line.
Additional Features:
CANbus Compatibility: Some vehicles may require CANbus-compatible bulbs to prevent flickering or error messages.
Waterproof Rating: A rating of IP67 or higher ensures the bulbs are resistant to water and dust.
Installation Advice
Tools and Preparation:
Gather necessary tools: screwdriver, gloves, and possibly a socket wrench.
Disconnect the vehicle's battery to prevent electrical shocks.
Accessing the Headlight Assembly:
Open the hood and locate the headlight assembly.
Remove the dust cover or protective cap behind the headlight.
Removing Old Bulbs:
Disconnect the power connector from the old bulb.
Release the bulb's retaining clip or twist the bulb to remove it, depending on your vehicle's setup.
Installing the New LED Bulbs:
Insert the new H4 LED Headlight bulb into the socket, ensuring it's seated properly.
Secure the retaining clip or twist the bulb to lock it in place.
Reconnect the power connector to the new bulb.
Testing and Adjustments:
Reconnect the vehicle’s battery.
Turn on the headlights to test the new bulbs. Check for proper functioning of both high and low beams.
Adjust the beam pattern if necessary to ensure it's focused and not causing glare.
By considering these factors and following the installation steps, you can upgrade your vehicle's headlights to H4 LED bulbs effectively.

I have a 2022 Subaru outback wilderness. I found out about these lights through a YouTuber who’s using them on his outback rig. I figured I’d give them a chance and ordered the same cyber series 3 lights. My girlfriend and I live in Colorado and drive all over the Rocky Mountains exploring. These lights have been an absolute game changer and have made trail riding so much easier. One of the best quality lights I’ve ever owned and would definitely like to get another set for the front brush bar of my outback. The Install was incredibly easy took me less than 20 minutes.

Very nice for price. Very bright and glad to have a round light option from Novsight. Installed on Wrangler Sahara JLU. Have also purchased Cyber 1 4.5” and Cyber 6 lights for Gladiator Mojave X, all great quality.

Easy installation, truly plug and play

Super Bright, The effect is better than I imagined

If you're looking for LED pod lights for your fifth-generation Toyota 4Runner, look no further than the Novsight LED Pod Spot Lights. Bright, well-made, and plug-and-play!

First - the boxing is supreme. The lights and covers are well protected and the box is sturdy. The lights are well made and have a good weight and feel to them. I love that you don't see these on every vehicles and that you can wire the Halos as DRL with TWO color options. I got the spot/flood combo and even being a jack of 2 trades - these lights are bright! You won't be disappointed.

I use my truck to go offroading in sand dunes in Had bought a light bar but it just made things worse these cyber series lights pierce through the sand giving me over 100 ft of clear visibility I need more!

These lights are pretty solid. Look very nice. Come packaged well. Easy to install. Provide a great amount of light output.

These lights are Great! Easy to install and look amazing! I have had a few people ask me about the lights and where I got them. I love the X look and with them double stacked you can do a set Amber and a Set white or both the same, they still look great!

The Halo SE is a rare LED pod light on the market that features red daytime running lights for first-time installers. It's very unique and I love it. I also bought their yellow and black covers. The yellow cover turns the lights yellow, giving you an extra color, while the black cover can be used for everyday protection. I personally recommend buying the cover.

Everyone asks for the name or where I purchased. Wish you guys gave out promo codes to people like myself with show trucks. Would be great to get money for referrals towards more products.

The 4-inch cube with side lights is incredibly bright. I live where there are narrow country roads with active deer. Thiese lights give me a much better chance to avoid a collision. I’ll be buying more for my other cars. Awesome!

I can't say enough about Novsight Halo Series lights and this light bar new addition to my rig is freaking amazing. I reached out to both Novsight and DV8 Offroad as I wanted to do something different and this was a great fit inside this front bumper by DV8 Offroad. Check out the picture.

Finally, I found the black version. I really like the Halo series lights, but they didn't have black housings before. I had considered buying a Halo series light and then retrofitting it with a black housing. But while I was hesitant, the Halo SE was released, and I immediately ordered it. This saved me a lot of time doing the modification myself. They also have red daytime running lights, which I can activate when I'm off-road, and I usually wear the black covers. This design blends perfectly with my black Jeep Wrangler. I'm very happy with this new series. Highly recommended for those with black or dark-colored cars.

I love the red/white daytime running light feature. It's well-made and easy to install. I lost a fog light cover and emailed the company to request a replacement. Their customer service is the best I've experienced in years! The staff is very polite.
