I have a 2015 T660 which has three amber tell-tail light as well as a white/red one at the top rear, on each side. None of them are working when I turn the lights on but the rear sidelights are ok. Is there a fuse for these anywhere? The Fiat handbook doesn't cover the coach built stuff and the Burstner handbook only seems to cover the interior electrics. I've put a call out to the dealer but not heard yet. Suspiciously all the side tell-tails were changed recently as they were letting in water. This is the first time I've tried the lights since they were changed!
