All late 90s/early 2000 era Ferraris were cursed with the large block of a yellow side marker (PN 147563 I believe). If they burn out, is there a dash light them comes on? (I have a 575 if that matters). Thanks If there is no warning light, I may make custom a white LED variant to swap in. I don't want to drill holes else I would go the Euro-spec smaller version.
The Euro lights are turn signal repeaters, not side markers. As far as I know, no warning lamp for the side marker lights.
The US side markers are usually just spliced into the nearest wiring for the front or tail position lights. No warning for these.
