I've fitted some LED DRL bulbs to my 2013 2.0 Elite Astra-J.
If I only get the bulb fail error message for the DRL LEDs and not the side lights, do I still need 4 load resistors, or do I only need 2 load resistors bridged across the DRL wiring? i.e. wires 3 & 4 of the bulb socket?
Thanks.
To answer to my own post. I only need a load resistor bridged across the DRL connections. None are required for the side light part of the DRL LED as no errors are being thrown up.
I'm aiming to disconnect the headlight multi-connector and use a multimeter to find the DRL wiring and tap into that as I think it'll make a neater job. I'll also pick up the earth in the connector wiring or add a tag to the wiring and connect directly onto the resistor body when I screw it to the bodywork to dissipate heat.
Also, it's pin 2 that's the +ve feed to the DRL, not pin 3, which is mentioned elsewhere in this thread for my 2013 Astra-J
Pin 3 is the +ve feed to the side light.
