it's not only the 1.8 g altis that has the optitron... i believe all the latest gen altis's have it....

my friend has this indiglo guages (for a rola) that aren't like the normal one's you see on the street... his has the usual blue or green background... but the numbers and dial are different colors... red with a hint of purple... and i forgot the other color... basta it's different...
