I've got a pair of them on my car.

The extra benefit is if you don't want to fit extra spotlights you have them built into the headlights.
You should consider wiring them so the low beam stays on at the same time the high beam switches on. The high beams point nicely straight down the road but don't light up the road directly in front of you.
Also you may have to modify and re-wire your indicators to house your sidelights as well as your indications otherwise you may fail the UK M.O.T. (The Cibie Biodes only house the main and high beam h1 bulbs and no sidelights). I've modified my indicators using decent bright LED bulbs along with a custom home made circuit board to drive them so they act work like a type 1 switchback bulb.
Brand new from Mini Delta
https://www.mini-del.../detail366.html a pair will set you back around £750 a pair including the import tax but plus postage (and that's in the sale) so I'd take good care of them and would highly recommend covering the lenses a decent dual layer of paint protection film to help protect the glasswork from damage.
