1973 280SE 4.5 sedan. You know, the two circular amber lights on the front that poke out. I'd like to remove the entire housing. You can't do it from inside the engine compartment, clearly you need to somehow remove the lens and front part of the chrome to get access to a bolt. But for the life of me I can't figure out how. From looking at eBay pictures it's clear the front part of the chrome does come off. My guess would be you need to rotate it, but that isn't doing anything. Is there a hidden clip?
