IN Stock
Part number
M28-11420 210 LUMENS
Give your Miata modern lighting technology. This is also the correct bulb for the reverse lights on an NC.

Make that car behind you see your brake lights!

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.

This 921 is the right bulb for the third brake light on the NA Miatas. It's also the bulb to use in the reverse lights of an NC. Usually, we'd recommend a red LED for this application but we have found that this white one works well. It's good and bright and does not have a pink glow, it's pure red. At 210 lumens, it's brighter than stock.

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. 

Sold as single. If you are using them for reverse lights in your NC, you'll need two.
