I have a pair of Bosch headlamps with the lenses marked 7102 R7 and 7102 R1. I originally bought these as spare for our 1974 Late Bay which was subsequently sold and replaced with a 1989 T25/Autohomes conversion. The headlamps on the T25 are Hella with lenses marked 7097 R7 and 7097 R1,
Does anyone know their headlamp codings to advise whether the 7097 are suitable to keep as spares for when the current ones need replacing. Thx for your help
