Give your NA/NB nice bright rear turn indicators! Available in your choice of light output..
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 1156 is the correct bulb for the front turn indicators on an NA or NB 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 amber, because you want to match your bulb color to the lens color.
Sold in pairs. Note that you will need a resistor or a new flasher to avoid hyperflash with these bulbs.
280 lumen: Diode Dynamics HP48
310 lumen: Diode Dynamics HP11
