Taillights

[TSB]

Just installed Spyder LED taillights on my 2015 Sierra. Dash is telling me check turn signal bulb and blinks fast. I installed following all directions, lights work but error message is persistent.  I even checked both lights and connections Again and disconnected the battery, still error message??

They system wants to see a certain amount of resistance for the flasher to work at normal speed. Since the LEDs use little current (low resistance) it's throwing a code as if a bulb is burned out. You'll probably need to add some resistance to the circuit. My bmw does the same thing & I had to add resistors to each led signal. That's my guess. Call your supplier for help
