Hi all. I installed Cointaker LEDs in my Corvette and love the look for the most part.
I will start with the backglass. The first pick is with standard 555 incandescent bulbs.
The second is with all 555 warm white Superbrights.
The third is with a mix of warm and cool white superbrights.
The last is a comparison of an incandescent, ww and cw superbright.
I really like it better with the superbrights. It really brings out the reds. Not yet certain if I like it more with pure ww or with the mix.

Here are the playfield pics.
For the most part I used color matched Cointaker Super brights or Super flexes for the medium and large inserts. I used single frosted leds for the small ones.
Exceptions are:
the yellows where I used warm white since they didn't have any yellow 555 superflexes.
White Extra Ball - warm white single frosted
White Catch me - incandescent since I forgot to order one. Will use a WW SuperFlex
The Red taillights - Used red single frosted
Blue Millions - Blue single frosted
Orange Pit in - Orange single frosted.
Don't like the Yellow single frosted in the backboard and race track GI. Not bright enough.
I put colored single frosted in the "Pit-in" and Xmas tree but had to take out the green ones because one bulb wouldn't turn off all the way. Will try another brand there.
The GI is mostly incandescents except for Orange clear singles under the engine and red single frosted in the upper lanes and under the exhaust.
The pop has a red 4LED. I don't like it. I wanted red 4+1s but they sent me the wrong item. Not excited about having to change out that burnt bulb. The ramp above it is a PITA to remove.

First pic is of normal incandescents. Second with the LEDs. Doesn't look as washed out in person. In fact, I think it looks really nice. I am sold on these Superbrights and will order them for all my DMD games.

This was my first go for the most part. Haven't tried the Ultras as I was skeptical of the supers. Thought they would be too bright. I went with Wolfpack's suggestions and I pretty much agree with them.
Taillights: I think the superbrights might be too bright in a small insert. The single frosted work fine for these small ones particularly when the bulb is aimed directly at the insert.
The superflex are great for sideways and angled sockets. The 555 are a super tight fit and require a lot of pressure to get them into the socket. So much so that I had to resolder one of the sockets on the circuit board. Still worth it though.

After playing a for a few hours tonight I am having second thoughts. They look beautiful enough but the strobe affect that some of them have is confusing as hell. Most are fine but some won't dim all the way and some others flash continuously, though at a lesser brightness. If I didn't know the game I would be lost.

Is there a brand of LEDs which only light up when you want them to?

I don't mind the quick on and off. Its the not turning off all the way that bothers me.

It is really fun. Great artwork, sounds and DMD animations. Has great flow and the game rewards you for shooting combos in several ways. There are a lot of small objectives like collecting spark plugs, spelling raucus, collecting speed parts, collecting cars, keeping the turbo targets activated to increase your points, shooting combos to increase your bonus, trying to complete the lanes to 8x bonus to also get the extra ball, becoming the lane combo champions and keeping the kickback active because the ball goes down the left outlane often. Unfortunately there are only 5 modes, Corvette challenge, Catch me, Drag-Race video mode, Engine multiball, and turbo hurryup, which repeat over and over, not including the 4 ball puzzle wizard mode to discover the Future Vette. I will say that unless you are good you won't repeat them too often in one game as those outlanes are brutal. I have also not yet made the final mode. There are only a couple of sucker shots, when the ball comes down thru the spinner slowly and if it doesn't go up the engine ramp all the way, it will drain SDTM.
I love the game, think it is very fun and really compliments my LOTR and IJ in terms of gameplay. But, due to the limited depth of the ruleset, I don't think I would want this as my only pin, especially for the going rate of it. I bought it for $1400 and spent about $100 to shop it which is a steal. Even though it is in my personal top 10, I would not have purchased it at the $2500+ most people want for it. While not an A list game, I do think it should rate higher than it is, like right around 50. If you ever get a chance to play it, spend some time on it and learn the strategy. It is very addictive.

I think I will replace the Superbrights in the Car inserts to single LEDs. This area is just too bright when several cars are collected.

Cointaker has awesome customer Service. They sent me the 4+1s to me no problems. He even called me to try and help me with the ghosting and asked if there were any other problems.

I got the patch from some other guy. Haase applied the patch to the Game U6 EPROM code I sent him. I now have to get a chip burned and see how well it works. Might take a few weeks. Wish I had an EPROM programmer.
I can send it to you but this patch only works for WPC machines. Not sure if there is one for Sterns.

Put the new ROM in with the additional delay. The delay helped with the ghosting but not the unwanted blinking. So now I have to decide whether or not to keep LEDs in those blinking inserts.

Yeah, the ghosting is mostly gone now. There are a couple which are stubborn but not so bright as to be confusing or bothersome.
I will probably go the colored 555s unless I can figure something else out.
Will those Noflix stop the flashing when they are not supposed to? There are only 5 or 6 inserts which do this.

Thank you.

As soon as I get my patched IJ Roms in and tested for blinking / ghosting inserts, I am going to order some Noflix Plus Superfluxs for the problem inserts. I will end up with a mixture of Cointaker and Noflix LEDs in each machine. I am hoping the Superfluxes are of comparable brightness to the Superbrights. Anyone seen both side by side?
Shipping is about $20 from them which isn't much more than most places charge to Alaska.

Update. Finally put LEDs in my IJ. I took the ones out of the backbox to test the inserts. It only had a few ghosting issues and no pulsing. Mostly with the green dogfight lights. Put in the patched EPROM and it got rid of the ghosting. This is with cointaker LEDs. I just wish the patch would have worked as well for the Corvette. I will order some Noflix for the Corvette and see how they do.
