After hearing the "Volvo equivalent" story I purchased one off of eBay.
It only cost a few bucks. Without dimensions it certainly looks the part.

When I got it in my hands, the bezel didn't look quite right. So I kept looking until I found a Fiat Brake Warning Light.

Unless the Volvo part I found was not the intended one, the "Volvo equivalent" is way too large.

If you do find one of the Fiat Warning Lights with text or graphics on it, it easily polishes off.
