I wasn't saying don't use them, I was just stating the fact that if you do make your own they would be illegal if they weren't DOT approved. Lord knows I do all kinds of thinks to my car that are not "approved" by the DOT, I don't care one bit.
If someone cared about using approved lighting on their car and wanted to change it you don't have to stay with just Mopar lighting. All lighting on cars is already approved, so you could put other manufacturers lights on your car.
One of my favorite side markers on cars are on the first generation Firebirds, they had a side marker shaped like a bird.
My favorite Mopar side marker is the '68 marker, that nice simple little round one.
