What about fake fog lights??
-Big 'kc' smilies -only the yellow plastic cover..
-Or here in Scandinavia it was 'Hella' plastic covers...
-Some cars looked like they had 6 fog lights!! (4 extras) -And actually some Swedes, Fins and Norwegians DID have them on in the winter..
-Also 'melodic horns' -a sure classic..
