Hey guys! Wanted to ask if anyone has had their horn go out (one moment it was working, and the next...

), and if so, what was the culprit? Do these horns go through a relay? Are they fused? Hopefully it isn't the actual switch, as it takes a while for us to get Triumph part orders!

:
Also, does anyone have thoughts or preferences on replacement headlamp bulbs...I fear this could be like opening up the great oil/tyre debate, so sorry if that is the case...

I ended up getting these Sylvania SilverStar bulbs that I am hoping aren't going to mess up the alternator or melt anything in the lamp housing area...(I've been told by three seperate bike shops that using too high a "kelvin"

could make that a reality, but the bulbs I got are 4000k's. Do you think those are safe for 'Tona?
Peace out! And thanks!
