When you're driving a car the size of a Miata, you want everyone to know when you're braking. These LED upgrades are brigher than stock and illuminate faster, which gives the distracted SUV behind you more time to react.
We use LEDs from Diode Dynamics because they're the best ones we've found. They're made in the US to high standards, not just the minimum price. They've got constant-current circuitry to protect the bulbs from transients and offer a three year warranty.
The 1157 is the correct bulb for the rear tail and brake lights on an NA Miata - as well as thousands of other applications around the industry. The 280 lumen option is a good replacement for stock. The 310 lumen option is the HEY YOU IN THE SUV PAY ATTENTION option. Both of these are red, because you want to match your bulb color to the lens color.
Sold in pairs. No resistor is needed to avoid hyperflash as these lights are not used for the turn indicators in this application.
If you have cruise control and you replace all of your brake lights (not tail lights), you'll need to add a resistor to keep the cruise control functioning. If you leave a single incandescent bulb, the cruise control will continue to function with no issues.
280 lumen: Diode Dynamics HP48
310 lumen: Diode Dynamics HP11
