If you are driving on the road, you will find that most police cars, long-haul trucks, or even work pickup trucks install red LED bulbs inside their vehicles since red lights give the best night vision possible.

Red light has a longer wavelength compared to white light, which regulates the autonomic nerves to stay in the best condition and greatly reduces fatigue driving at night. They also don’t require your eyes to dilate as much, meaning you can keep your night vision while still being able to have some light.

Why do the red LED lights benefit us?

To Maintain your night vision

Red light is a great help for the people who drive at night. When you need to pull over at night or take care of work, the red light will be gentler than the white light and won't be as fatiguing due to the prolonged use of interior lights. AUXITO 194 red LED bulbs are equipped with 14 high illumination 2835 SMD LEDs to improve visibility at night, and it's not as harsh as usual bulbs.

Warning function

If your rear side marker light is red, it can improve visibility in foggy and snowy weather, alter the car behind you and maintain a certain driving distance. In addition, some car owners also install red LED lights at the door lights to warn the car door is not closed in a striking way.

Make your vehicle look cooler

The final reason why some pickups (or cars) especially have red interior lighting is just that it looks cool. Modifying your vehicle to be different from stock is a lot of fun, including interior lighting.

The AUXITO red T10/194 LED bulb is almost the same size as the 194 halogen bulbs in stock. The thick plug design ensures the 2825 led bulbs fit tightly for all T10 wedge types, compatible with 194, 2825, 168, 161, 175, 174, W5W, etc

And with the non-polar design of LED bulbs, plug and play for the instant bright red light in your dome light, map light, parking light, door courtesy light, license plate tag light, trunk cargo light, and side marker light on your 12V cars or trucks
