I asked the bulb color question and now realize I didn't need to, but appreciate all the feed back. I remembered that sometime many years ago 18 or so, I purchased a LH side NOS complete Mach 1 sport lamp. I hadn't see or touch it unit today and after pulling the chrome bezel off I see that the original painted amber bulb is still in it. I have not tried to remove the lens as it is literally stuck to the pretty much hard original gasket and I don't want to damage anything and it will go back on the shelf for maybe another number of years ;-)
