Instrument cluster lights

I have a 2000 Speedy .. About 12 years ago I swopped the clock surround for a Rizoma billet surround. Haven't touched it since ... however ... slowly over the course of time the bulbs have been blowing so I decided to upgrade to T10 LED bulbs. The backlight is now blue on all 3 dials and seems to work ok .. However .. I swopped the bulbs on the idiot lights for T6.5 led's and now the indicator light only flashes if turning right (or left if you turn the bulb round) .. The petrol light and engine management are permanently on while neutral, high beam and oil warning all work fine.

Has anyone else changed their bulbs and made everything work ok ?

Thanks in advance
