What are CAN Bus LED Bulbs?

when we say CAN Bus LED bulbs, they are the easy plug-and- play LED lights bulbs which are made specifically for the vehicles built-in CAN-Bus system. These bulbs work with your vehicle's advanced computer system, so when your vehicle's computer reads them, they respond back correctly.

To see if your vehicle operates with a CAN Bus system, simply remove the bulb you're looking to replace, start your vehicle, and if you have a "Bulb Out" message on your dash you have a CAN Bus system.
