Find the Right Part Sizes for Your Vehicle

Series Recommendation

Once you've confirmed that your vehicle uses a T15 bulb for 3rd brake light bulbs, side marker light bulbs, or reverse light bulbs, then you just need to consider what features you'd prefer in an LED bulb. AUXITO makes it easy for you to choose from a wide range of T15 LED light bulbs in a variety of lumens, sizes, designs, and more. Check out our T15 bulb selection guide to help you understand the AUXITO T15 light bulb series!/p>

3A18 Series
LED Light Bulbs

This 912 LED light bulb features a top-mounted cooling fan for superior heat dissipation, ensuring a clearer view when reversing your vehicle, and an extended LED bulb lifespan.

42H Series
LED Light Bulbs

AUXITO's hottest option - The 54H series with the compact lens on the top can achieve a good spotlight effect, and reduce light scattering, while the 360° illumination design greatly enhances the visibility of Reverses.

CSP Series
LED Light Bulbs

The CSP series of bulbs are the brightest of the reversing light options, so if you have a T15 reversing light bulb model and are looking for maximum brightness, then the CSP range will fit the bill perfectly. However, it should be noted that they have a large fan at the rear, so you need to make sure you have enough space to install them before purchasing.

FAQ

Q: What is T15 LED?

A: T15 refers to a specific type of LED bulb size or socket type used in automotive lighting. The number 921 is used to denote the bulb's size and specifications. 921 bulbs are often used for backup lights, dome lights, and other similar applications in vehicles.

Q: Is T15 the same as 921?

A: T15 and 921 are not the same but are related. T15 refers to the bulb size or socket type, while 921 is a specific bulb size designation. T15 bulbs can often serve as replacements for 921 bulbs and vice versa, as long as the physical dimensions and electrical specifications match.

Q: Can I use one for a replacement reverse light and the other for a high-mount brake light?

A: These AUXITO 921 912 led bulbs are designed for reverse lights only, we don’t recommend installing them in other lights which may cause the bulbs to fail soon. In addition, the cargo light bulbs at the high-mount brake lights of some Ford models can be replaced with T15 reverse light bulbs.

Q: Can you use LED lights for reverse lights?

A: Yes, LED lights are commonly used for reverse lights in vehicles. They offer several advantages over traditional incandescent bulbs, such as higher brightness, lower power consumption, and longer lifespan. When upgrading to LED reverse lights, it's important to choose bulbs designed for automotive use and to ensure compatibility with your vehicle's electrical system.

Q: Why is my reverse light not working after changing the bulb?

A: Several factors could contribute to a reverse light not working after changing the bulb:

  • Incorrect installation: Ensure that the new bulb is properly seated and connected in the socket.
  • Electrical issues: Check for blown fuses, wiring problems, or a faulty switch that could be affecting the reverse light's operation.
  • Bulb quality: Poor-quality or incompatible LED bulbs may not work as expected. Make sure you're using bulbs designed for automotive use.
  • Canbus systems: Some vehicles have advanced electrical systems (CANbus) that might require specific LED bulbs designed to work with them.

Q: What color should reverse light be?

A: White. They are used to warn other vehicles and people around the car that the vehicle is about to move backward. The reverse lights also provide some illumination when the car is backing up. Reverse lights on a vehicle must be white in color, and these come standard on all vehicles.
