Honestly I think you'll end up with more problems than you'll solve.I like the idea of having programmable functions such as auto-off indicators, flashing then permanent brake light, and deceleration activated brake light.
It also affords the opportunity to go keyless ignition via either an electronic fob or smart phone or both!
My only concern about fitting it is that it may bring up loads of OEM Fault Indicators - not actually problematic in themselves but very annoying to always have to look at!
