canbus adapters
Some cars, such as the 2007+ Dodge, Chrysler, Jeep, GMC, BMW, and Mercedes-Bens, require the CANBUS adapters to be installed together to avoid the flicker or warning message.
To confirm if need CANBUS or not, just remove the original headlight bulb and check if the dashboard show BULB ERROR or not.
For American vehicles, we advise the Resistor decoder. For European vehicles, the Capacitor decoder.

Solid 8/10. Shipping took a while, but I think it came from outside the states so I’m not complaining. The lights are brighter than shit and I’ve had my fair share of assholes that like to flash me. I’ve had one instance where the lights on the left and right do not sync up, meaning one light would be white and one yellow, for example. To fix it, I just rapidly turned the lights on and off. Even came with wired in resistors. No complaints, no regrets. Would recommend.
Great product well worth the money. My only issue is that it didn’t fully fit my car so i had to do some modifications and switching the lighting options don’t always work at first but then later on work
Lights were not quite as bright as I expected but still happy with my purchase.
Pretty lights. In the city so can’t really tell how strong the lights are until I drive in the country. Would get again though
Product is great, i am a returning customer, but the most recent purchase was dissappointing. It seemed like it was a return, it was not as protected in the packaging, my first purchase had stickers , paperwork with instructions and glass tubes over the led itself to protect it, this one did not, i also ordered a led replacement for my reverse lights, and it came red. Nothing on the package said red and when i entered what i wanted on the site, my cars reverse light, it was the option given. Shipping took longer than the forst time also, like 3 times as long. I might not purchase from the company after such a quick decline in Quality. I was so very impressed the first time and recommended the product and showed off to everyone, after this purchase im a bit embarassed to say what happened.
