I think I found another

I was taking headlights apart for plating buckets. I believe the painted ones are 240z and the unpainted are 280z

The screw tabs for the lamps are also different

They must have blacked them after assembly because the tabs and screws were all painted black

Can anyone else corroborate?  I have never seen this before.

So here's another data point

These are the lights that came out of "Lily"

Green overspray but I don't see any black. The also have the slotted screw tabs. So I would say the slotted screw tabs are for 240's

One more
