Upgrade your brake lights with a brighter and more responsive LED lighting solution. Each bulb features 9 high-power 2835 SMD LEDs for a bright, noticeable red output, while the built-in flashing function provides an extra visual warning when braking.


Each AUXITO LED bulb uses 9 high-power 2835 SMD LEDs—3 LEDs on the top and 6 LEDs on the sides—to deliver a brighter and more noticeable red light than traditional bulbs. The red illumination also gives your vehicle a clean, refreshed look.

When you step on the brake, the bulbs flash red three times and then stay steadily illuminated. The quick flashing sequence helps draw attention to your vehicle during braking before switching to a constant red light.
Ideal for the Center High-Mounted Stop Light (CHMSL), 3rd brake lights, and other compatible brake light positions. The red LED output provides a clear and noticeable signal when braking.

LED technology provides bright illumination with low power consumption, helping reduce energy use while offering a longer service life compared with conventional incandescent bulbs.

Built-in intelligent IC circuitry helps provide stable performance and minimize bulb-out warnings, flickering, and other common LED issues on most compatible vehicles.

Designed to match the size and socket configuration of compatible factory bulbs. Simply remove the original bulb and install the AUXITO LED bulb—no complicated wiring or modifications required.

Designed for applications using the following bulb/socket sizes:
T15 / 912 / 921 / 906 / 904 / 902 / W16W
Note: Bulb compatibility can vary by vehicle and lighting position. Always check your vehicle owner's manual or compare the original bulb before ordering.
Please check your vehicle owner's manual or compare the original bulb to confirm the correct bulb size and application before placing your order.

Installation was difficult, but that's true about all Ram Rebels given that the entire headlight assembly needs to be removed. Didn't need a CANBUS decoder which is great, but I did need some headlight enclosure covers that were a little bit deeper to allow more room for the heatsinks. Also, the adjustment to clock the lights was very important since the high and low beam sockets are oriented differently. Once I got them installed and tested, I was very happy with the amount of light each one produces. The low beams are focused (I have projectors) and don't blind oncoming cars. The high beams are ridiculously bright. We'll see how they hold up.
Good Enough
These were the only HB4 9006 bulbs I could find with a removable collar. I had to drill this to move the grub screw due to MX5 mounting position to keep at 3 & 9 o'clock positions for best beam pattern.
Definitely recommend the product. Package got to me in 24hrs (yes actually) and came as described. The process itself took me 5 minutes total to do both sides. No tools were needed - you just go thru the wheel well and push the bottom tab to pop out the existing side markers. They almost blend in perfectly with my plastics and provide a more sleek look I’m going for. The white running light perfectly matches my white day time running lights in my headlight assembly. Can’t beat it for the price
Initially received & installed Y13 H4 9003 LED's. High beam indicator did not turn on. They sent out the CanBus Decoders. Those solved my issue. Thank you.
