Cibie lamps can be sourced at truck wreckers , just don't ask for them by name. Tho shouldn't pay more than $100pr these days.
To wire them up, they must be on separate switches (prs of lamps) and only able to work while high beam is activated ..best to run relays for all lights separately. Once they are working consider installing Hid kit to them. ...it'll turn a dismal winters night into a bright summers day! !
My mk2 escort ran 2up/2 down for over 10yrs and at the and of driving it i fitted Hids to the spots , it makes the high beam look yellow in comparison if it can be seen in the brightness !!
