Review on Alla Lighting CAN Bus T20 7440 7443 LED Bulbs Amber Yellow Turn Signal Lights: Upgrade your Blinker Lamps with Plug-n-Play 7444NA 7442NA WY27/8W CANBUS Replacement by Jason Carranza

The first pair I received was probably a throwback someone randomly threw lights in! But that's not the point of this review, I ordered two different sets of bulbs for my turn signals that didn't work or would require additional parts (relay or resistor). Spend the extra money and get headlights with built in resistor or CANBUS, especially if you have RAM or a European car. It's only the first day, but so far I haven't had any problems with my Jetta. If I were to use cheaper LED alternatives I would have to replace the alarm relay or use a resistor, which I could have done but didn't want to do. I'm glad I spent the extra $20.
