New LED 1157 bulbs for rear lights. Do I need ballast resistors or an electronic flasher - or both? This is for a negative-ground BT7.
What happens if I put LEDs in the front lights - more resistors?

I had to put ballast resistors on mine when I put LEDs in back. I put them on the Flasher Relay terminals 3 & 7 to ground. As for changing the flasher, see if the old one works. I ended up changing mine to an electronic one, but not the one usually sold, because I didn't change the front lights. The fronts are light enough and they look better if the color temperature is the same as the headlights.

Either or. LEDs don't draw enough current to activate a std., 'normal' flasher unit (note LED running/stop lights work without either on a BJ8). If I was to do this, I'd probably go with the SS flasher.

I took the line of least resistance (pun intended) and used an electronic flasher with these on my BN1:

1157 LED Bulb with Stock Cover - Dual Function 36 SMD LED Tower - BAY15D Bulb

The BAY15D plug-and-play LED replacement bulb is suitable for vehicle applications. The 360° beam angle reduces hot spots and provides a wide viewing angle for all-over light emission. The stock bulb cover encloses the LEDs and gives the bulb a traditional look. Designed to last 30,000 hours- 25...

Previous experience with installing LED turn signals/brake lights and running lights with resistors was the proverbial pain and using the electronic flasher instead was a no brainer....
 
I installed both front and rear LED lights in the running/turn/brake lights and kept The original flasher relay . Everything works perfectly.
