I fitted a sequential shift light to my 172 Cup but removed it after a week as it was very erratic. Mostly when slowing down it would flash like crazy, so returned it to the manufacturer. Dunno if it was just that particular type but it was basically no good. The manufacturer said they've had problems with them fitted to Clio's due to a weak signal? Dunno how true that is, but it does have two pulses from the coil so I'd imagine it would under read by half, but so long as it's just a shift light and not an RPM counter it should be fine. I'd imagine the Burpspeed car runs it's lights off its standalone management, not the original Renault ECU.
