transistors - Make three respective LEDs blink with an LM3914 in dot mode

I'm trying to figure out how to make in the below schematic, LEDs D2, D3, and D4 blink respectively while the LM3914 is in dot mode when their on state occurs. Basically this would act like a warning indicating that you should recharge soon, and D1 would just be solid on when it's respective on state occurs (dot mode). I would like to do this with no 555 timer or micro controller either, using as few components as possible. Edit: I'm using a 10 segment LED bargraph.

Answer

You can use the flashing bar display circuit shown in the LM3914 datasheet (figure 20). To have multiple flashing LEDs in dot mode you just have to add a diode between the timing capacitor and each output that you want to flash.
