Thanks for the reply
Yes I am aware that this topic has been discussed before ,
The reason I ask is because I was confused , I already have the dual element sockets andI thought I was missing some steps .
First running a wire from the centre BL to the signal lights isn"t going to work
Am I to run a separate wire from the S/L switch to the rear signal light wire
You mention a second dedicated wire on the S/L switch one going to the centre brake light which it already does correct.and the other to the T/S switch This is what confuses me .
You can tell I am new at this .
