Not sure if this will help but the Lucas L594 has the following specs and is a glass lens and definitely "E" marked
Glass Lens Outer Diameter: 2 3/8" (60.3 mm), Glass Height: 1 1/2" (38.1 mm)
Rubber Boot Outer Lip Diameter 2 7/8" (73 mm), Boot Smaller Outer Diameter 1 5/16" (33.3 mm), Boot Depth 2 1/8" (54 mm)
The L488 is about the same size as well
72mm diameter rubber base with 54mm diameter flat glass lens
and best lead I can offer is this - but not cheap!
