Quoted from barakandl:Something I have been doing to tame down the seizure blinking of GI relays is to put a low ohm power resistor across the relay. When the relay is open the resistor keep the bulbs on, but at a much dimmer level. That way you still get an effect, but its not so jarring. Data East/Sega/Stern games have too much blinking for my taste and the instant on/off nature of LEDs makes it worse.
Does this work with leds though?
