Installing headlamp bulbs

[Grumpy Goat]

All 5 of my low beam bulbs I replaced give no indication of not working when I turned the bike off but icon and non functioning bulb showed up when I started the bike. No other bulbs have stopped functioning on my bike.

All same for me, except maybe the count of bulbs. I might be up to 3 blown. Other changes are due to my choice based on desired light colour.
