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:
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.

Best lights ever…super bright you won’t be disappointed
I’m very pleased with the quality of the product It makes a big difference on the road and the car stands out! Keep the good work! I definitely recommend
I bought the Y19 series 9005 and i love the brightness. I can see them in the daytime
These lights are phenomenal. I recently got a 2021 Ford F-250 XL and I am very familiar with LEDs as I like to see at night. As some might know, H13 bulbs are dual-purpose lights, meaning they act as low beams and high beams, and my truck has 4(2 per headlight). These claim 12,000 lumens per bulb, so I'd have 48,000 lumens, and let me tell you... I believe them. Installed them and just went for a drive at night to test them out and holy crap, my low beams are the brightest low beams of any vehicle I've ever been in and I've been in some bright light vehicles. High beams are pretty bright too but the low beams... I don't know if there is a legal limit for lumens or what but if there is in the state of Michigan I'm probably past the limit as I got brighted 8 times on my 30-mile drive.
Very bright replacement for fog lights and the brights are finally bright enough to have other people turn theirs down.
