Each amc7135 chip on this board supplies 350mA. The board will supply 2+amps, so one must desolder a couple of these 7135 chips, taking it down to the prefered maximum amp draw. The momentary switches are connected in parallel with the on board switch.

Driver base hooks to harness, driver base also uses paracord to secure base to white led housing. Cord is threaded through the holes, and then melted at the end making it unable to come loose. Features independant control of white and red leds, 4 brightness modes, as well as sos, flash. Uses nitecore F1 18650 powerbank, which is rated at a 1amp output. Both battery and powerbank have protection circuits for safety of the dog, as this design is NOT WATERPROOF, and shouldn't be used in the rain or anywhere it could get water on it.

The white led driver is set at 700mA current limit, and the red is set to 350mA current limit giving a total of 1050mA current draw when both sets of leds are at maximum brightness. I have used a thermal imager and the heatsinked driver boards, and heatsinked leds remain at a safe temperature. All parts were made with t-glase, although, abs or a more flexible filament might be the optimal choice for the buckle clips.
