    I've installed LED's in some of my GI (AC) circuit. While the lamps have a nice glow, when the ball is around there appears a strobe effect on the ball. Is there any reason I shouldn't install a bridge rectifier on the GI bus to convert it to DC, thus improving the strobe effect?

    I already have obsessive compulsive disorder (OCD). It's pinball at the moment. Will a bridge rectifier help? I'm looking for a low budget solution and already have spare bridge rectifiers. Thanks for any advice!

    If you are using "AC" LEDs, they already have a bridge built in. If you're using inexpensive bulbs without internal bridges, an external bridge would help.

    Thanks for the comment. Yes, I have installed inexpensive (5 cent) LED's. I will install the bridge on the GI bus then and see how that works.

    What game? What kind of LEDs?

    PROBLEM SOLVED. I had assembled 12V LEDs in my GI that was 6v. DUH. After replacing the GI LED's with those made for 6v the strange effect was gone. The LED's I am using, which I assembled myself, work in AC or DC. They cost me less than 5 cents each! Actually, the LED component was free (Harbor Freight), and the resistors I had laying around the shop for more than 30 years. If I were to go out today and buy the LEDs and resistors, the cost would total 5 cents!

    UPDATE: I've upgraded the LED's I assembled myself specifically for GI lighting without the use of a rectifier. I use two SMD5050 chips, one connected forward polarity, the other reverse. There is no noticeable strobe effect, and they are a little brighter than compared to the ones with only one chip.

    This is cool. I have some really nice SMDs down stairs which might work well. Huzzah for rolling your own.
