I just got a new 7 Ah SLA battery from Zbattery for $13.87, plus a new plug and forget charger. I will be mounting my old 5 Ah SLA to my wife's bike for her 10 mile round trip--I am hoping we will only have to recharge both batteries at night.

I have been pondering how to add turn signal lights, plus a good brake light to my bike. I think I have found a good source for cheap LED lights, but I have not figured out exactly how to mount the switches for both the turn lights and to actuate the brake light. I admit the brake light is not all that necessary, but I think the turn lights, especially when waiting at a intersection, would be most helpful. I would appreciate any comments on how to mount switches on handlebars.
