Here are some of the best full replacement switches I have found but they fail to list the diameter of the handlebars they fit. Since these are all DOT approved it seems there is no law about having an off switch on motorcycle lights. I also read my local DOT lighting laws and it never mentions that the lights must be on at all times the bike is.
I have seen a fair amount of accessory toggles that are simple kill switches. I guess I could install one of these in line with the existing light control to achieve my goal. Rewiring the entire control might be more of a pain.
Thanks for the feedback guys.[/QUOTE]
The down side to this, is that over time the switch will develop unwanted resistence and lower the availible voltage to the headlight, causing a dimmer than normal headlight. even the factory headlight high/low switches do it.
not saying it will happen, but a very real possibility.
and then you will have 2 switchs with even more resistence.
BUT BEING SEEN AND SAFTY SHOULD BE YOUR #1 CONCERN
