Ive got autometer ones. I dont like them! I didnt pay alot for them from the store. But there the green is a rubber condom you slide over the bulb to make the bulb green which makes the guages supposly turn green (match the factory ford guage green). The final result is a very dim porly illumited guage that has a hint of green . I think they are the Sport Compact series. I will evenchually upgrade to Issipro or Dipricol guages
