+### On my ESP8266 when I flash the sketch the LEDs light up, is this normal?
+Yes it is normal for both DMA and UART to have this side effect.  
+The UART is used to program the ESP, both DMA and UART are using the low level hardware that is also used for serial/uploads; so this can happen.  They are reacting to the serial data being sent across the wire and get fooled into thinking its something when its just code being flashed.  
+
+Since the LEDs need 5v, when I prototype I usually run a switch that I can turn them off when I upload; and the final project just doesn't get flashed.  
+
+NOTE:  OTA (over the air) flashing should not cause this.  
+NOTE:  Some have said that using the UART method causes less flashing.
