Installing LED's in the '69 rally gauge cluster


I have pulled the dash cluster out of the '69, to convert the ammeter gauge in the rally cluster. In addition, I thought I would put #168 LED's in the cluster. I know someone has done this before and posted on here, I thought it was Mark (Cdnpont), but it wasn't.no My question is how do I determine polarity of the socket? The polarity is marked on most LED bulbs (the long contact leg is positive), but how can I tell if they are being put correctly in the socket? Especially, with the cluster being out of the car, I want to make sure they are functioning properly before reinstalling the cluster. Any advice on this or reviews of the best LED bulbs to use would be much appreciated! Thanks!

A topic I know something about. ... Did a full dashboard changeover two years ago.

Bulb quality: I paid dearly for Philips Ultinon 168 LED bulbs, some through Canadian Tire, some through Amazon.ca. I didn't ever want to remove and reinstall again, due to cheap bulbs.
Installation: It says on the Philips packaging outright that their bulbs are directional, meaning that if it doesn't light up, you remove it, turn it 180 degrees to reinstall and it should work. That may address your problem you mentioned, through just trial and error. My Can Am has some very limited fibre optic lighting as well. It's just a normal 168 that faces into a FO wire, so I figured what the heck put a LED bulb on that too. It worked.
Overall: You will be very happy with the difference in lighting when switch from regular to LED. It made a huge difference in legibility and clarity at night, primarily because the bulbs are 'daylight' (5000 lumen) versus warm or soft white (I think around 2700 lumen).

Good luck!

I'm sure it was davepl that put the LED's in the dash of one of his 69 B-body cars.

Thanks Mark, that picture is a good one. I will try to verify the positive spots.

Thanks Bob, I currently have some Sylvania Zevos bulbs with a lifetime warranty that are probably comparable to the Phillips because they werent cheap either! I know about flipping the bulbs around, but what I was looking for, is a way to put them in knowing they are being put in the socket and installed on the printed circuit the correct way without a power source, as the cluster is out of the car.

Thanks Clint...it was Dave, its all coming back to me!

Just a question, are these replacement bulbs dimmable? I have been in situations where I needed to dim the dash lights to improve visibility in poor weather.
Thanks,
Paul

Since it's out of the car... With the cluster lighting, signals and high beam indicator, I'd just ground the cluster body to a spare battery neg. Then take a positive probe off the battery and touch the corresponding connection in the main connector lead in for the lamp(s) you're configuring. In the dark, one at a time, you'll soon find which way way the socket should be oriented to light the LED. Then move to the 4 idiot light sockets, positive common at #1. Then probe with negative 9-12.

Here's a legend for the board and plug,

 The ones I have are not dimmable. Not sure if they make dimmable ones.

 Thanks Mark. That was what I was figuring I would have to do. Really appreciate the illustrations...pictures speak volumes! In my case, I will have to refer to the rally cluster chart from your "standard gauge to rally gauge conversion" post!biggrin

 For LED's, you'll need a separate underdash dimmer,
