Switch on Headlamp

[Lifter]

Hello Gang,

I just bought this bike last month.

The first time I went to look at it, i noticed this strange switch on the headlamp. I thought it was strange place to put a switch (not really easy to reach) but i wasn't really familiar with the particular model or cruisers in general.

Well, the switch has a short in it and needs to be replaced, but i was hoping to find out ideas on what the heck it was installed for in the first place.

Here is what it does:

OFF - Break RUNNING light, rear blinkers and Spedo light OFF
ON - Break RUNNING light and SPedo light ON. Rear Blinkers.

** Does not effect Headlamp or rear signals **


I initially thought that someone installed a Headlight Bypass for better cranking power on start or some kind of modulator but the headlight itself and rear signal lights are un-effected.

Thanks in advance!
Brad
