This Is A Simple How To LED Your 620 Truck (Because You And I Both Know You Can't See Your Gauges At Night To Save Your Life) :rofl:Posted Image

^^ Simple Thing I Made That Shows Where The Bulbs Are

*Please Note*

It Is Best To REMOVE The Whole Gauge Bezel W/ Gauge Cluster To Do This
This Is On A 78 Non KC With AC, I Know There Are Variations But The Gauges Should Have The Same Lights :huh:

Now You Might Be Thinking To Yourself... "Why The Hell Do I Need To Get These Tiny Ass Bulbs When They Have Some That Fit Right In"
If You Want To Get The Different Bulbs, Go Right Ahead.
I Did The Math And The Other Bulbs Will Illuminate About Twice As Much As Your Other Gauges.
With These All 3 Of Your Gauges Will Be The Same (In Brightness)
*Also* - These Bulbs Are Polarized, If They Do Not Turn On Simply Flip Them Around.

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

awesome writeup, but everyone please note that the tach lights are nto as bright as they seem in the pictures, you will need to get some higher power bulbs with more led's for the light output to seem similar.

Thank You Zeusimo!

I just finished this upgrade and... Really... these are much brighter than stock. I went green. Though similar to original, the green is a different color than stock, if that is important. Also, the dash light dimmer works with the LEDs just fine.

Observations (using Zeusimo's numbers)

1) After removing the screws and nuts off the back, support the tach and don't let it fall on the floor. With the guts out, you can then access the green plastic bulb covers.

3 & 4) After the clear gauge cluster cover has been removed (it's held on with clips), the black bezel over the idiot lights & gauges lifts out. You then can remove the green plastic bulb cover in the middle. Also, with the bezel out, you can then access the green plastic bulb covers behind the Spedo.

After installation of the bulbs into the Spedo cluster, I'd recommend that you plug the assembly back in and test. It will be easy to make any adjustments necessary before final installation.

And the tiny ass mini bulbs used do illuminate evenly. :thumbup:

Well this is fucked, I just ordered all the lights following the links and I got sent bayonet base bulbs not wedged ones. Your links are wrong and now I have a bunch of lights I can use. Its a good thing they're cheap or I'd be more upset.

 

Fix the links to the proper bulbs.

 

Correction, the red Dummy lights and the blue High/Pass bulb are wrong. I have those in bayonets not wedge ones. Other then that everything else was fine and works. I went green with everything and am happy with the choice. Ill post a photo tomorrow.

Are the wedge base the same as the miniature base? It's confusing when the links are different
