Why Headlights Matter for Your 1999 Mazda Miata
The 1999 Mazda Miata (NB) is an icon among sports cars—lightweight, agile, and built for the joy of driving. But when it comes to factory headlights, owners often find themselves wanting more—more brightness, more clarity, and better nighttime visibility. Whether you’re restoring your NB Miata or upgrading for safety and style, updating your headlights is one of the most effective improvements you can make.
In this guide, we’ll break down the best headlight options, what to look for when buying, and how to choose the right fit for your roadster.
Factory Headlights: Classic but Outdated
The stock 1999 Mazda Miata headlights are halogen sealed beams. While they offer a retro charm, they’re no match for modern lighting standards. These headlights tend to yellow over time, reducing light output and visibility. For daily driving or spirited night rides, this can become a safety concern.
Upgrading is not just about aesthetics—it’s also about performance and peace of mind.
Best Headlight Replacement Options for 99 Miata
1. LED Headlight Conversion Kits
One of the most popular upgrades for the NB Miata is an LED headlight kit. These provide superior brightness, lower power consumption, and a longer lifespan compared to halogens. Many kits are plug-and-play, meaning no complex wiring or modifications are required.
You can find great options from trusted aftermarket brands. Look for products with high lumen output and a clear color temperature of around 6000K for optimal white light. A good example can be found from this source.
2. Projector Headlight Assemblies
For a more premium feel and sharper light pattern, consider installing projector-style headlights. These headlights use a lens to focus the beam, reducing glare and improving nighttime visibility. They also allow for aesthetic customization with halo rings or DRLs.

3. HID Conversion Kits
High-intensity discharge (HID) kits were once the gold standard before LEDs took over. While they require ballasts and a bit more setup than LEDs, HID lights still provide significantly more brightness than halogen and work well with projector-style housings.
To ensure a clean install and legal compliance, use DOT-approved HID kits from this source.
Installation Tips for First-Time Upgraders
Upgrading your 99 Miata headlights doesn’t have to be complicated.
- Check Compatibility: Make sure the kit is specifically designed for NB Miata or is a standard 7” round headlight size.
- Aim Properly: After installation, align the beam pattern to avoid blinding oncoming traffic.
- Use Relay Harness: This ensures consistent power supply and protects your car’s factory wiring.

Style Meets Function: Headlight Customizations
Beyond brightness, some owners want their Miata to stand out. Consider customizing your headlights with:
- Smoked or Black Housing for a stealth look
- Angel Eyes / Halo Rings for BMW-style flair
- Sequential Turn Signals for modern touch
These add-ons are available as standalone accessories or integrated into upgraded headlight assemblies. Popular picks come from this source.
Legal Considerations and Local Laws
Before switching to aftermarket headlights, check your local regulations. Some states have restrictions on color temperature or require DOT or SAE approval. Ensuring compliance helps avoid tickets and ensures your safety on the road.
