Overview


Instant Brake. The factory incandescent 3rd brake light bulb on most vehicles lights up in a glow which takes a moment to turn on. A modern LED upgrade provides instant response which can alert other drivers on the road earlier while also providing a modern LED appearance. This third brake light LED is a great upgrade in both style and function.


Quantity. As different trim levels often come equipped with different third brake lights we have listed bulbs individually here. Please double-check on your vehicle and select the quantity needed to replace all of your bulbs.


Correct Color. You'll see that we only offer a red color option which is correct to SAE/DOT red" requirements. This provides the most output through the red lens of the 3rd brake light as the red lens acts as a filter only allowing red light through.


Brightness. All Diode Dynamics LED lighting is rated with accurate measured lumen figures not calculations or guesses. We test the true output in-house and provide you the real numbers to compare.


Reliability. Diode Dynamics LEDs are built with constant-current inductive circuitry along with transient suppression. While more expensive than simple bulbs this allows Diode Dynamics LEDs to last for years with no flickering or failure.

Sturdiness
Color: Black, Size: Standard - 4 Panel
Not so sturdy. It worked well for its intended job, but, it has to be secured to the floor for long term use.

Wobbly but Usable
Color: Grey, Size: Standard - 4 Panel
A bit wobbly, but good enough for the price when you need a solid background for remote work calls.

Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
I absolutely love this 4-panel room divider! It was super easy to assemble — I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function — highly recommend!
