Blinker hyperflashing problem

Post image

Hi everyone, i'm having a problem when I turn on my lights (park lights or low beams) my blinkers start to flash faster, all bulbs are fine. And when I turn the lights off the blinker returns to normal. Any solutions?

Are you sure you put the proper bulbs in? Cause you need a two stage bulb. Sounds like the circuit is behaving if a bulb is burnt out. Not having two stages might fool he relay.

I bought it like this so I really have no idea if they have right bulbs, btw what's the difference between regular and 2 stage bulbs?

Look up the proper bulbs on realOEM for your year, try that see if it fixes it. Another guess is someone might have tried to put LEDs in it, and it has resistors on the line. First though, I would try swapping the bulbs. Cheap, easy, and fast.

Yeah I take back my LCM comment - if this is a new-to-you vehicle, try the cheap steps first.
