This is the look I'm after for the CIBIE Iode-45 bumper lamps. I really love the clean, simple and unobstructive look of the 90 degree metal mounting bracket https://pbase.com/9146gt/image/159920041

Here is the aluminum mounting bracket on the Miles Collier factory 914-6 GT https://pbase.com/9146gt/image/159920043. Obviously a more sturdy lamp support, but more intrusive also. This photo shows additional detail of the CIBIO Iode-45 lamp bracket at the front bumper and lower valance https://pbase.com/9146gt/image/22285786. The front bumper of the GT will have to be notched so to clear the mounting lamp bracket

Here is the bracket again in Peter Jenkins's 914-6 GT project car https://pbase.com/9146gt/image/70172388, very nice indeed https://pbase.com/9146gt/image/70303372 - Thank you for the photos Peter!
