The Mazda MX-5 (NB) is the second generation MX-5, produced from 1998 to 2005. The model maintained the MX-5's philosophy of being a lightweight, front-mid-engine, rear-wheel-drive roadster while offering numerous performance improvements, but lacked the retractable headlamps of its predecessor.
Factory-fitted options included HB4 9006 / H7 / HB3 9005 halogen projector headlights, manufactured by Koito. The prefacelift reflector type headlight uses H4 halogen bulbs.
The halogen projector facelift version features a HB4 / 9006 or H7 halogen projector, which produces an average light beam even when new. In many cases, its light output has been further compromised as a bulb and general aging cause the reflective layer to peel off.
The single-halogen setup features a 2.5-inch projector, designed in the late 90s. These projectors are known to lose their reflective layer, where they become black inside, causing dangerously low light output.
Needless to say, buying new or used original headlights for your Mazda MX-5 Miata is not recommended. But there is, fortunately, no need for that. There are upgrade kits that will fit inside your existing headlights.
These complete retrofit kits provide you with superior brightness and durability and they are also very affordable. Since all components are brand new, they come with a 2-year warranty. Additional benefits over OEM headlights include Canbus-proof designs and effortless halogen-to-xenon conversions. What’s more, the leveling systems will work without any adjustments to the headlight connectors, and you can use any ballasts you might already own to save further on xenon upgrades.
No matter which retrofit upgrade kit you pick, you will improve the light output considerably, making for safer and more enjoyable driving. And, of course, your Mazda MX-5 NB2 will look awesome with the luxurious bright light of the latest bi-xenon or Bi-led technology.
