OK that would be great thanks .... yeah I all ready did a hi gloss white in my cluster. Do you have pics of your extra bulbs mod to ?

here is mine

Thanks for posting up the link for the bulbs. I ordered and found them in my mailbox two days later.

Heya Slambone were you able to get that pic up loaded yet for me ? And also did you have pics of your extra bulbs mod ?

I installed mine today. Picture doesn't do it justice on the reg bulbs.

Just installed my new dash with the LEDs looks great..
Now does anyone know the bulb size of the parklights?

[chevy2tom]

Just ordered mine

[WOLFMANmike]

Mine will be delivered today

[WOLFMANmike]

Did mine today ... very happy with the results

i took mine apart and sadly there is no lighting from the factory on my column

will these also work with a warning light dash (no gauges) ?

Yes, the cluster back-lighting is basically the same for gauge & warning light clusters. The bulb count & location vary, but electrically they're the same.

However, you have to watch out for the polarity if you're using LEDs to replace the actual warning lights. The "oil", "hot", and "cold" lights all have ignition power fed to one side of the bulb. And the switches on the engine ground the other side to illuminate the bulbs. If the polarity of the LED is backward compared to how the socket is wired they won't work.

Also, an LED probably won't work correctly in the "gen" light because that one is wired in parallel with a 10Ω resistance wire.

Just ordered a set! Thanks for the ebay item number.

If you want dimmable LED's, usually the best way is to use strip lights. You just have to run them around the inside and stick the wires out one of the holes, then seal it all up. Hook up the power and ground and you'll have LED's that work on the dimmer switch.
Also strips will help eliminate any 'hot spots' or areas around the bulb that appear brighter than the rest of the cluster.

No pics as I haven't done mine yet...

Thanks for the Tip! I just finished installing the new LEDs.

I got a set of LED's from the suggested ebay vendor all the bulbs worked except the turn signal inicator light only works for "right" I switched it back to the original bulb and both sides work. I tested the wires they both work. Is it a matter of getting a specifically designed LED bulb? or is that just a bad bulb?

Bad bulb but check it anyway put it in the other blinker side that is working and if it works then your issue is not the bulb ... but I'm betting a bad bulb

I should have clarified, I have a '63 and it only has 1 indicator and it flashes for either side.

OK still easy just do it in a working socket any way and check the bulb that way like a socket that is for the cluster lights

That single turn signal indicator setup is going to present an issue when using an LED in that location.

The single indicator is wired across the left & right signal light wires so the active signaling side is positive and the inactive side provides the ground. As a result, the polarity at the indicator bulb changes with the direction. And as I mentioned earlier, LED's (being diodes) are polarity sensitive so that's why yours is only working when indicating a right turn.

Now, there is such a thing as a bi-polar LED that will light up with current flowing in either direction. It's basically two LED's connected anti-parallel inside the same package. Many of them are bi-color as well, lighting up red in one direction and green in the other for example. However, I'm not sure if anything like this is available in a package that will plug directly into your existing indicator socket. But you might want to check with the vendor where you bought your LED's to see if they do happen to offer one. Something like that would be perfect for that type of single indicator application.

Thanks for the info! I had a feeling the LED bulb would be problematic.

I was taken to school about this in another thread here. The best suggestion was to hook the LED to a proper ground then attach a diode to each of the two wires for the indicator then to the positive of the LED. This makes the light work for both sides and the diodes keep power from backfeeding through the system due to the lack of resistance from not having the incandescent bulb.

what about just useing all the LEDs and then only the incandescent bulb just the the turn signals ??

Thanks for the tip, got mine installed tonight. Looks much better.
