Think I have gotten all the lighting working properly..but I have a question for those who have a '78 C3:
My emergency flashers seem to function fine..
Works w/car on/off front side lites, front grill lites, brake lites..But rear side lights DO NOT FLASH?
Is that normal? side lites rear have 2 wire connection , lamps new and work as running lites/parking..Any input..Jim

'75

Rear marker lights are marker only, not supposed to flash.
