Another vote for exposure.
A MK2 reflex on the bars and a joystick on the lid (very old and pretty much blown away by the reflex even it’s on low). Both 2nd hand, the reflex I rented for 24/12 then bought off exposure. Both phenomenal.
Also have a race maxx MK1/2 for the commuter hooked up to an 80 lumen rear light (I forget the exact name).
