Yes, they ghost, but it hasn't really bothered me so far in the system 3 games I've LEDed.

I haven't yet tried non-ghosting bulbs, but I imagine they would prevent it.

I have a Gladiators right now that i am installing LEDs into. Non ghosting are definitely needed. They eliminate all ghosting. I'm using Comet and PBlife brands.

I generally use sunlight bulbs for the playfield GI most part. Cool white for the backbox.

I am using all frosted cool white for the playfield. Putting a mix of frosted blue and purple along the light strip at the back of the playfield.
Color matched the inserts.

What's the deal with LEDs in the pop bumpers? Seems like they won't work in Wipeout and haven't bothered to try in Big Hurt since probably the same result.

I haven't noticed any issues.

Although, if it's a 555 lamp socket, sometimes you have to adjust the wires on the bulb to make sure they touch the socket contacts. Or, sometimes the lamp socket is faulty and needs to be replaced.

I put the cheapest Chinese bulbs I could buy in bad girls with no ghosting or flickering whatsoever.

Doesn't Wipe Out pulse 12v through the 6 v lamp and uses it as a flash lamp when the pop is hit?
As far as those bayonet bases in pops, they suck. I seat the LED so it lights up and then apply a couple dabs of hot melt glue to stabilize it. Works like a charm. Chances are you'll never have to replace the lamp again.

Where did u order those, exactly....

Ali express. It was 40$ cdn for 100 bulbs.

I've used several different leds (standard and non ghosting) from different places (mainly PBL) and don't remember having any issues in any of my system 80's,A's and B's. Mike

Wipe Out does something for sure because I've burned up LEDs in those sockets.

Just got Gladiators finished. Cool White GI. Purple and blue accent across the rear light bar. And some creative colors in the inserts. Plus a purple strip in the drain. Looks very nice!

Is the hardware much different for Gottlieb Premiere than it is for earlier Gottliebs? I've got a Alien Star downstairs that I can test out for you.

The system 3 machines share strobe lines for both lamps and switch signals. I've found that cheap bulbs always seem to ghost in the system 3 games. Earlier Gottliebs were just fine with non ghosting lamps. My Hollywood Heat had no ghosting at all with bargain LEDs.

Yea, the system 3 System was a pretty significant departure from the System 80(a/b) architecture. Although I always was pretty curious how Gottlieb managed to pulse those bulbs with a higher voltage. They did that in a bunch of games. Caribbean Cruise being the first, I believe.

Did the lamp matrix run at a higher voltage (then strobed down to 6 volts) like Williams did?

Hi everyone. Running into a problem with the LEDs on my Mario Andretti (system 3). Everything had LED installed when I bought it, but several of the insert lights on the playfield appeared to be burned out (very noticeable on the "track" of cars in the center playfield) Upon closer inspection, the bulbs usually come back on if I push my finger sightly against the side of a bulb suggesting in just not getting a good connection. So I pulled a bulb, and compared to some of the other bulbs I have, and maybe it's just an illusion, the base appears slightly smaller. For the sake of troubleshooting, I used a few bulbs from an email bag o'bulbs and they seemed to work ok, but are ghosting. I guess my question is two fold: anyone else run into base size issues? (Maybe they are simply the wrong size???) Any suggested fix for using the existing bulbs without buying all new Ghostbusters? Thanks!

Just put standard comets into my Gladiators and I will say that it ghosts pretty significantly, to the point where the non-active "ghosting" bulbs are almost as bright as the active bulbs. It looks great otherwise though. Might need to invest in some non-ghosting for the critical inserts.

You might want to use some calipers and measure the hole size from below on the Ghosting inserts.
Gottlieb was notorious for drilling 10.5-10.8mm.
Regular bulbs fit, but non ghosting might not, making inserting them from below the playfield impossible.
The solution is non ghosting Flex heads, and bend them pointing up into the insert.

You may or may not have this need.
