Hi Fella's. My AU2 fairmont ghia, the aerial switch is illuminated with head lights on, and I'm pretty sure the other 3 ie TC, demister, an Central locking all are illuminated, with head lights on. I will check tomorrow as those T3 seem the right size / style, was trying to separate the actual switch today, of my TC, it has a globe in there but doesn't illuminate hence, why I'm here. Will post tomorrow, for future references. thanks. Any final info would be appreciated. cheers.
