Not been on this thread for some time but it is related to the original build.
The Furrari failed its MOT due to headlight missalignment. The headlight beam was way out of where it should have been ( LH side only). Investigation showed that one of the lugs that hold the bulb in place had broken off allowing the bulb to twist. Only solution was a new projector unit. Ordered a new Hella unit from Car Builders Solutions. Fitted it and went for adjustment and retest. Failed again. This time because the beam patten kicked up the wrong way, as though it was for a LD drive car. No, CBS's catalogue said it was for a RH drive car.
I phoned CBS, no, Hella listed this as RHD. CBS contacted Hella and got back to me within half an hour.
When The Furrari was built, Hella made two units, a LD and a RH drive one. DNA of course fitted a pair of RH drive ones. In the subsequent years the design has been changed so there is only one style, and it’s a universal one. They all come out of Hungary set to LH drive but all it needs is a tweek on the (hidden) adjustment screw to convert it to RD drive.
So if you get new Hella units for your car, look at the back of the unit. Below where the high beam wires go into the housing is another plug. Pull it our, turn the screw clockwise, put the plug back. Job done. Easy when you know how. To do the job, less than a minute. To find how to do the job, about a week. Hey, that’s kit cars.
