I got a 6n2 I’ve  put hids in but the passenger one keeps flickering can Anyone point in the right direction on what to do please? 

Check the connections, there might be corrosion on the connector, a loose connection, or even a broken wire. Give them a waggle with the lights on, see if it flickers in response.
 

Alternatively, swap the lamps round first, see if the fault swaps too. You might have got one that’s dodgy. Doing  this will prove the fault is with the HID or with the wiring circuit.

Will try this. Someone said on here that behind the passenger indicator there is yellow clip disconnect that but I can’t see no yellow clip anywhere.
