9004 headlight bulb
The 9004 headlight bulb is another type of dual-beam bulb commonly used in automotive headlights. It's similar to the 9008 (H13) bulb but differs in its design and specifications:
Dual-Beam Functionality: Like the 9008 (H13) bulb, the 9004 bulb is designed to serve as both high beam and low beam headlights in vehicles with dual-beam headlight systems.
Electrical Specifications: The 9004 bulb operates on a different electrical system compared to the 9008 (H13) bulb. Specifically, the 9004 bulb uses a different pin configuration and is wired differently from the 9008 (H13).
Physical Design: The physical design of the 9004 bulb includes a specific base and filament arrangement that differs from the 9008 (H13) bulb. This means they are not interchangeable without modifying the wiring or using adapters designed for conversion.
Brightness and Compatibility: When choosing a 9004 bulb, consider factors such as brightness (lumens), color temperature (Kelvin), and compatibility with your vehicle's make, model, and year. Ensure the bulb meets regulatory standards for automotive lighting in your region.
It's essential to verify your vehicle's specific bulb requirements before purchasing replacement bulbs to ensure compatibility and proper functionality. If your vehicle originally came with 9004 bulbs, replacements should also be 9004 bulbs unless you are willing to modify the wiring or use conversion kits designed for different bulb types.

These lights have a very solid construction and are very bright. Quick delivery and overall very satisfied.

My name is Tim Hendrickson and I just want to give everyone my experience with novsight headlight bulbs . First of all excellent customer service and fast shipping. I have attached pictures of my novsight N60 Ultra Series LED H13 headlight bulbs in my truck. I have bought headlight experts head light bulbs and xenon headlight bulbs and I am here to tell you novsight is the best in my opinion. Extremely bright. If you are second guessing it stop just do yourself the favor and place your order and you can thank me later. I am speaking on the N60 ultra series but I have no doubt that all their headlight bulbs are amazing. They come very well packaged in a nice box . I am very pleased and definitely a on going customer. Hope this helps anyone looking at giving nova sight a try .

Great tent and matches my needs perfectly and the look I was going for.

It’s hard to stay elusive with these uniques and impressive Off-road lights. The DLR’s give off a supernatural glow while the main lights make it hard for anything to hide in the shadows! Love these lights!

The lights are so nice and bright. Was also very easy to install. Must have the anti flickering resistor.

Design is great and the lighting exceeded my expectations. Installed on 2025 Jeep Mojave X. Orange is a perfect match.

Great quality, I really like them and they look great, I’m definitely buying more of this products

Plug and play in 2017 Hyundai Accent fog lights, no decoder needed. Perfect amount of brightness and matches OEM beam pattern.

Really love this lights! Even for a small 4 inch set up they light up the night very well, I did got a better harness set up, but still a great set up

Went from 55w Morimoto 5500k HID to the N60 LED and it fixed the issues I had with output and could not be happier. Been running Morimoto HID in 3 vehicles for years. I finally have what I’ve been left wanting! Highly recommend the N60 series

I really like the design and the ways in which they turn on, they are different and they are not expensive, and most importantly they light up very well

I bought two pairs of X-Series and installed them on my 2024 GMC 3.0 AT4 Sierra. The installation process was so simple. Lights are beautiful, look good on my truck and make my truck stand out than the others of the same model and year.

I ended up cutting the box and not using it. Connected the lights to my wireless auxiliary box and wham! They look fantastic!!!

After my wife complained about the headlights on our 2013 Chevy Volt, I immediately looked for LED replacement bulbs. Considering there is such a wide price range, I chose a Volt bulb that was inexpensive and well reviewed. It was a plug and play installation. It took me less than 10 minutes to complete. As you can see in the before and after photos, the light is 18 degrees brighter than before. The high beam setting is great as well. I highly recommend these bulbs!

They look very pretty, they have clear lighting and are very strong, made of good material and very interesting as seen in the photos, I recommend this product.
