Just wanted to share some pictures of my 12v light setup. I am using the Optronics driving light housing. A 20w 12 degree spot in the front and the Vellman strobe in the rear. I am using the BatterySpace 4500 aMh NimH battery and easily get over a hour run time. The battery box is a waterproof food storage container. The little black protusion on the clear battery container is a switch. There is a second one on the other side. I also use a helmet mounted 10w spot running on it's own 2000aMh battery that is stored in a side compartment of my hip bag. You can never have too much light
Thanks again to all that shared their advice and experience.
