So I have fitted the cafe racer 5 3/4 led units in the standard caterham bowls, it's a simple job, watch out the 3 spring clips don't fly away and wear goggles as they are tricky....around 1 hour to do both.
Minor wires to joint for led side-drl, otherwise plug and play.
Mine cost about £104 a pair in February 2021.
More than happy with them, no need to spend more and fully mot compliant.
Lots of 7 owners I know have these fitted .
Message me if you need more information
