LEDs not only give your vehicle a clean, modern look but, with proper use, will outlast any halogen bulb and HID bulb! Low energy draw, high lumen output, and instant on/off LED technology out shines stock bulbs in every way. Which bulbs are used in my vehicle? Check Sylvania automotive lamp replacemnt guide , you can select the year, make, and model of your vehicle, then select the application you want to replace or upgrade from stock. What does CAN Bus mean? CAN Bus means Controller Area Network Bus. This system monitors your vehicle and reports operating conditions. CAN Bus systems are commonly found in European vehicles such as BMW, Audi, Mercedes, Volkswagen, Porsche, and in many American vehicles. While most late model American vehicles have CAN Bus systems, it is always good to check with your vehicle dealer to see which system your vehicle has before purchasing electrical products. When do you need Warning Canceller? Some vehicles with cmplex internal computers(such as Audi,BMW,Jaguar,Mercedes,etc.) might report on-dash errors or flickering on the headlights. The warning canceller fixes the dashboard warning and flickering effect. Bulb Out Dashboard Error: On some vehicles, the dashboard will report as if you have a headlight bulb missing or burnt. It does not affect the headlights functioning, but the light on-dash will be on. The warning canceller fixes the issue. Flickering Issue: This happens when your vehicle does not recognize the new headlights installed. When turning the headlights on, the vehicle's computer does not understand the signal back from the headlights hence thinking they are still off. This triggers the headlight flickering effect. The warning canceller solves this issue. LED Advantages: Very low and efficient energy consumption than halogen bulbs & HID Bulbs Compared with HID bulbs, LED bulbs Light up instantly, no warm up period Low voltage protection, high precision constant current driver chip Longer lifespan than HID and halogen bulbs Light can be controlled easily in color and intensity Easy to install a LED headlight conversion kit (1) We will ship your item(s) within 24 hours.
