DUAL COLOR: White with Amber DRL

Main White LED Light with Amber DRL (daytime running lights)

White LED -- Super bright and crisp white beam pattern. It will definitely provide you with enough light needed for all of your adventures. However, these are only for off-roading and can’t be used on the regular road. They will blind the in-coming traffic and also violates road safety.
Amber DRL -- amber DRL “daytime running lights” acts purely for aesthetics. Since it doesn’t give out much light, you can use this amber DRL feature on regular roads, it doesn't blind in-coming traffic.

DUAL COLOR: Yellow with Amber DRL

Main Yellow LED Light with Amber DRL (daytime running lights)

Yellow LED -- used in poor driving conditions such as dust, fog, snow and rain. It reflects through air particles much less than the white light. Therefore, making it ideal for poor driving conditions. For off road use only.
Amber DRL -- amber DRL “daytime running lights” acts purely for aesthetics. Since it doesn’t give out much light, you can use this amber DRL feature on regular roads, it doesn't blind in-coming traffic.

**Please note** The yellow lens alters the look of the amber DRL, making it appear a little darker than with the white lens. Check the photos to see the difference.

Combo Pattern: combined spot and driving optics offers a balance between the distance and width
Uses TIR (Total Internal Reflection) lens is different from our the regular slim light bar. The TIR lens collects all of the light from the LED and directly leads them to where you need, drastically reducing glare and improving total efficiency.
Higher light efficiency: brighter, longer irradiation distance
Housing is upgraded to 304 aluminum. The surface is UV polyester powder coated to prevent against UV, salt water, corrosion, fading and scratch resistant.
Equipped with thermal management system that automatically adjusts the brightness output according to the external temperatures

👍Our light kits are for off-road use only.

Wireless 8 Circuit Wiring Harness 2.0

➡️Special Features (only featured in this wireless 2.0)

Sleep Mode (Power-Saving Mode): If the input voltage of the Control Box falls below 13V (±0.2V), the Control Box will enter the sleep mode after 6 hours (default) of consecutively inactivity, then all loads will be shut down immediately and the Control Box will not respond to any commands from the Wireless Control Panel. When the input voltage rises above 13V (±0.2V), the Control Box will be awoken.

Low Voltage Protection: If the input voltage of the Control Box falls below 12.2V (±0.2V), the Control Box will enter the low voltage timing mode. After exceeding 30 minutes, the Control Box will start the low voltage protection, then all loads will be shut down immediately and the Control Box will not respond to any commands from the Wireless Control Panel. When the input voltage rises above 13V (±0.2V), the Control Box will exit the low voltage protection.

Ultra-Low Voltage Protection: If the input voltage of the Control Box falls below 11.6V (±0.2V), the Control Box will enter the ultra-low voltage timing mode. After exceeding 10 seconds, the Control Box will start the ultra-low voltage protection, then all loads will be shut down immediately and the Control Box will not respond to any commands from the Wireless Control Panel. When the input voltage rises above 13V (±0.2V), the Control Box will exit the ultra-low voltage protection.

High Temperature Protection: If the temperature at the center of the Control Box's circuit board exceeds 100°C (±5°C), the Control Box will start the high temperature protection and immediately shut down all loads.

➡️Wireless Harness Specs

The main control box has 8 circuits, ranging in different amps.

(3) 10amps

(2) 20amps

(3) 30amps

The fuse box is made out of high thermal conductivity die-case aviation aluminum housing. Allowing it to resist high-intensity impacts and is fully suitable for extreme off-road conditions. The surface is powder coated with UV-resistant polyester for weather resistance. The internal two-component thermally conductive mixture conducts and dissipates the heat generated by the circuity more quickly and effectively.
