Install Guide

Product FAQ
Q: Is this item plug and play?

• Yes, this item is plug and play, and includes all bulbs/wiring necessary for full functionality upon installation. The headlights are plug and play for those with the stock Halogen OEM headlights. It will not work for those with the upgraded LED OEM headlights.

Q: Is this item full LED?

• No, this item utilizes halogen bulbs for the low and high beams, although the C-light is LED so your parking light will be LED, and if you utilize our switchback harness for the C-light, then your C-light can function as your signal light as well.

Q: If the C-light goes out, how would I replace it?

• Please reach out to us for resolution options if you lose C-light functionality, as the LEDs are long-lasting and we would assist with troubleshooting this issue and offering resolution options for this.

Q: Do the boomerang LEDs function as Daytime Running Lights (DRL) by default?

• No, you will need to purchase a separate add-on DRL harness to run the boomerang parking LEDs as your DRL.

Q: Do you offer LED or HID upgrades for this item?

• We do offer an optional 3000 Lumen H11 LED upgrade for the low/high beam functions if you would wish to upgrade to LEDs. We do NOT offer HID upgrades for this light.

Halogen vs HID vs LED

Auto lighting

The current Auto lighting industry has three standard bulb technologies integrated for headlight use. The three headlight standards are

1) Halogen, 2) HID, or 3) LED based.

Advantages for LED


There are a few ways to check but the requirement is that you must have stock setup.


“Bi-Xenon” means high and low beam are both genuine xenon HID, but the real (OEM Standard) bi-xenon is that the Low and High Beam uses the same xenon bulb and ballasts in the same projector which that projector has an electric controlled shutter built in (in front of light bulb but behind the glass projector lens).



Auto-Leveling is the new feature that was introduced in the late 90. Auto-Leveling is a feature that incorporates a motor/servo built in a headlight which operates/actuates the headlight's inner adjustment mounts, which moves the Beam output angle up and down (either by car's ECU/OBC automatically or via a Self-Leveling Switch inside the car cabin). This headlight feature is to provide the best lighting angle for the headlight beam output, which helps maximizes the driver's visibility while also doubling to help not blind the oncoming traffic.


Introduced to the high end vehicles around year 2003, the AFS differs from Auto-Leveling that moves up and down, instead moves the headlight beam left / right to help driver see the upcoming curved road better. Rather than the mechanical linkages employed in earlier directional-headlamp systems, AFS relies on electronic sensors, transducers and actuators. Other AFS techniques include special auxiliary optical systems within a vehicle's headlamp housings. These auxiliary systems may be switched on and off as the vehicle and operating conditions call for light or darkness at the angles covered by the beam the auxiliary optics produce.

A typical system measures steering angle and vehicle speed to swivel the headlamps. The most advanced AFS systems use GPS signals to anticipate changes in road curvature, rather than simply reacting to them. To know whether you have AFS system or not, you can see if your headlight beam moving left / right when you change the direction of the steering wheel, but again that is not 100% scientific, so the best way is actually call to any dealer and give them your VIN number and they will be able to let you know if you have stock equipped AFS headlight or not.


DRL stands for Daytime Running Light which originally was developed and used in countries that are more prone to foggy conditions and it is a safety feature which has now become standardized by many car manufacturers. In some countries, it is by law required features (such as Canada). Please note that the DRL feature is not site specific on a vehicle. As long as the supposed “DRL” Light remains on during the day (with the Parking Brake disengaged) and turns off OR becomes dimmer (automatically) when the “Parking Light” Light is engaged, then the supposed light should be your DRL.

There are two main types of Day-time Running Lights Halogen DRL vs. LED DRL. There are other types of DRL, however to keep things simple, we will focus on the two main types. The picture example above shows the different projections between LED and Halogen.

DRL may use your low beam or high beam or others, but it is normally supplied only with 27.5W power versus the original 55W halogen bulbs used in the halogen low beam or halogen high beam. So it might create an issue if you upgrade a genuine xenon HID system to the headlight if the DRL function is using the new xenon HID system. This is because standard xenon HID needs 35W to power it, while DRL is only supplied with 27.5W, it means the system is underpowered. Flickering, error message, not able to fire it up would be the common issue if you have DRL powering the HID system. To solve it, the installer can either disable the DRL feature altogether or do minor re-wiring so the DRL is powering something else other than the new HID light.


Kelvin temperature is commonly mistaken for the heat or brightness output of the HID Bulb. The Kelvin temperature only deals with the "color" output the Bulb emits as each colors covers a certain Kelvin range. The "K" for instance in "8000K" represents the certain bulb color temperature output, and it's the abbreviation for the word Kelvin. Below is a chart showing you the range of the Kelvin temperatures. Lower Kelvin temperature will emit a more red output. The normal halogen lamp color temperature is rated at 3200K.


Car manufactures have recently implemented Sports packages for certain of their chassis by creating a sub-segment that widens their market and to fulfill market demands. Sports packages are commonly associated with performance cars such as Audi, BMW, MBZ, and Lexus. Each car manufacturer have their own Sports package brand.


Most car's production period (chassis life) is around 4 to 6 years. In between each chassis production period the car manufacturer usually will make minor improvements (design-wise and/or engine-wise) after 2 to3 years after its initial chassis introduction. This is to update the car's look and to stimulate market. The first half of the production period (before the manufacturer updates the chassis) is commonly referred as Pre-Facelift, whereas post half of the chassis production period is referred as Facelift.

Life Cycle Impulse (LCI) - BMW term for facelift or update to existing series. Life cycle inventory, part of a Life cycle assessment to stimulate sales. LCI is typically known as "Facelift" for BMW vehicles.

Perfect if you dont want to do it yourself

Just what I was looking for at a great price too


Absolutely love them. Changes the look of the whole car

Danel R.

Install was very easy with all the provided harnesses and guidance from the YouTube video. Final product looks amazing and is a worthwhile upgrade over OEM headlights.

Evan C.

The installation was straight forward and completely plug and play; the fitment was great as well. The instruction video was very well shot and easy to follow.
The quality of the headlights are very good and I'm loving every second of it!

Marcus D.

EZ install. The Fuse Harness is perfect! I had to literally just insert a fuse tab to my use box and plug the connections directly to the lights. Saved me sometime and works good.
