Release date: September 18, 2025

Brightness 575%! Available in two colors: easy-to-see 6000K and weather-resistant 2800K.

Compared to the original LED fog lamps, the 575% achieves better brightness and visibility.
The highest level of brightness of 4600lm among L1B standard bulbs! *Value for one vehicle with two bulbs.
It provides wide, bright light from the front, which is not possible with the dim genuine fog lamps, making the fog lamp practical.

White⇔Yellow color switchable L1B bulb

It can be switched between two colors: 6000K white light, which is easy to see during normal driving, and 2800K yellow light, which provides excellent visibility in bad weather.
The brightness is 4600lm, the highest level of the L1B fog bulb. *Total value for both left and right
In addition, it achieves a wide light distribution from front to back that is far superior to the original fog lights.

In addition to delivering intense brightness, it also achieves an astonishing 97% high-speed maintenance rate, which is directly linked to the designed lifespan of the LED bulb.
This means that LEDs have a long lifespan and are highly durable.

Color can be easily changed with the fog lamp switch. Comes with memory function.

The fog lamps can be turned on and the color can be changed using the original fog lamp switch.
It also has a memory function that stores the color.
The color that was last turned on for more than 5 seconds is remembered, so you don't have to change it the next time you ride.

Built-in fan for maximum cooling effect

In order to achieve high levels of brightness and color switching functionality, the driver unit is separate.
It takes in outside air more efficiently than the rear fan for cooling.

Easy to install! Same size as genuine LED bulbs

The dimensions are almost the same as the factory L1B fog bulbs. Low noise design prevents interference with the latest factory equipment such as radios and sonar.
Separate driver type cable coupler on specification.
For vehicles with special screws on the lamp fixtures, two tools are included to make removal easier: a special screwdriver and a special wrench.
The dedicated wrench is made of 1mm thick stainless steel, making it difficult to bend and easy to use.

*This applies to genuine LED fog lamps that use L1B standard LEDs. Please refer to the vehicle compatibility chart for details.
