Hey tylerw, those are some watt sucking lights you're looking at! 110w for the pair. Your KLR doesn't have as good of a charging system as a car does. You might want to consider some LED's like the Denali D1's from Twisted Throttle. FYI, they are introducing Denali D2's that are a big improvement over the D1's. They claim that the LED's are as bright as 55w halogen's. Regardless, at 20w for two bright LED lights, it won't suck the life out of your battery. HID's are another option to save the juice.
