Do the lights come with loading resistors, or does it tell you anywhere that the leds should pull the same current as normal side lights plus indicators.
Are you experiencing any bulb error lights on the dash?
Some further info as had a play with them today.
I re-wired so the strip LED and DRL + wires were connected to the car Indicator and sidelight + wires.
I then took the - wire from strip and earthed it to an engine bolt.
The - wire that was attached to the old led bulb I taped off
So when I switch the car on the DRL comes on followed by 3/4 sweeps of the Indicator (1st Issue) and back to DRL
If I press the Hazard switch the Indicator comes on and stays on and all works fine and when switch off DRL back on
Now when I press the Indicator stalk it comes on fine and then after about 3/4 sweeps the Indicator noise speeds up (fault detection symptom I believe) and then 3/4 sweeps later the DRL comes on.
If I press either the Indicator or Hazards again the Indicator noise is fast as before and after 3/4 sweeps back to DRL
So my VCDS is playing up but I am thinking it is causing a fault in the Indicator and switching off the Indicator power. My next stp was to clear the fault and see if works again until causes a fault again so then something to start with.
I looked in the Control box of the Strip and their seems to be a resistor on the DRL wire but not on the Indicator wire so could this maybe be the issue
