Upgrading to LED is one of the most effective ways to modernize your Mazda's appearance and safety profile. Since your RX7 uses a single 6052 LED bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. Don't forget the LED Fog Light fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
