Hello I have a 2004 s type 4.2 v8
I hope someone can help me with this question
I have had two headlight bulbs fail in a couple of weeks
Yet nothing came up on my instrument cluster
But when I removed a indicator bulb a got a fault message on my cluster saying right hand front indicator light not working

Is the can bus only for the indicators

I even removed rear taillight bulb still no fault on cluster only when removed rear indicator bulb

I have had enough of replacing halogen bulbs
And looking at going led
Does anyone know if headlights are meant to be can bus compatible
Thanks darrol
