I noticed my self-cancelling indicators occasionally wouldn’t self-cancel at some roundabouts and junctions. This is because (as per my regular tin top too), the [physical] turn angle on the roundabout is not enough to engage the self-cancelling mechanism.
Also, as it’s a tad noisier in the open-topped environment, and somewhat brighter: a.) I can't hear the click of the indicator relay, and b.) the L&R LED indicator warning lights are not in my line of sight. So I am usually not aware of these flashing away merrily in the fresh air. So to mitigate this condition I’ve put in an additional single, combined L&R indicator warning light within my direct line of sight.
Had to be careful on this one as I didn’t want too big a warning light as that would’ve been the elephant-in-the-room of my dashboard configuration; so one of those CBS green mini warning lights and a metre each of Green/Red and Green/White cable to extend the L&R L9 and L16 power feeds on the dash’ loom, and a couple of CBS diodes was all that was needed to make and enable this modification.
I also polished up an M8 washer to function as a supplemental bezel because the bezel lip on the mini LED is only 2mm wide and is no way wide enough to grab onto the dash covering lip without slipping under. I also epoxied a larger washer on the back of the dashboard to better support the bulb retaining nut, as the brittle GRP edge [on the smaller diameter component fixings] can tend to cause the edge to flake and crumble.
