Frequently Asked Questions (FAQs)

1. What is a CANbus bulb?

CAN Bus LED bulbs are LED bulbs which are made specifically for CAN Bus-equipped vehicles. These bulbs work with your vehicle's advanced computer system, so when your vehicle's computer reads them, they respond back correctly. What does CAN Bus mean? CAN Bus means Controller Area Network Bus.

2. What is the difference between 7443 and 7444 bulbs?

All four bulbs are dual filament which means they are two light bulbs in one. 7443/NA is rated at 12 volts 21/5 watts and 7444/NA is rated at 13.5 volts 28/8 watts which means 7444/NA is supposed to be a little brighter.

3. Do you need CANbus for LED?

Why do LED bulbs sometimes need a CANbus adapter? If your vehicle's lighting is not producing the wattage your vehicle expects, the canbus system will detect this, and interpret it as a fault - again triggering an error message.

4. Can you use LED bulbs for turn signals?

No worries—it's an easy fix! LED lighting draws much less power and lasts way longer than standard incandescent lighting that comes stock with most vehicles. Although the reduced draw of LEDs has advantages, replacement of turn signal bulbs with LEDS will cause what is called hyperflashing.
