UK models have lights permanently on and I rarely if ever use high beam so I reckon I'll be OK.
Also, this mod is purely for extra daytime visibility as I can't remember the last time I rode at night.
I bought these for high beam, just in case I ever go down the diode route with low / high beam on together:
