Using SMD LED Bulbs in Cluster
#21
Le Mans Master
I can confirm with personal and extensive unwanted experience, the cluster does not have to come OUT, but I did need lower the column, disconnect the oil line and speedo/tach cables, and push the cluster forward a few inches away from the firewall in order to gain access to the bulbs.
That's true. I decided to go ahead and pull it. Not much left holding it in there anyway.
I saw no point in further contortions.My hands are the size of a catchers mitt.

they can be replaced without pulling the cluster you need one of these tools they work great http://forums.corvetteforum.com/atta...1&d=1333508703

Yeah, I hear you. I was trapped in my dash-light-fuse-blowing hell and was tired of pulling the cluster out. I had already completely replaced my new main harness with a borrowed one just to run a test and then put my main harness back in the car after the test was over.

Is there an advantage to the green color, other than personal preference (and that your Vette is green, as is mine)? I assume the bulbs you used come in white too.

Bulbs are impossible to change with out pulling the cluster and to do that would really have to pull the column as well it took at least a hour and a half on my back under the dash to hook it all back up bulbs can be found all over in all kinds of colors id recommend getting a bulb with at least 10 SMD's on them (individual lights)

9 in the cluster
2 in the clock
on a 1967
it only had 3 working orignal bulbs back there when I pulled it out figured the lettering in the gauges was green so that was my idea behind using green
Thanks

I used some LEDs for turn signal indicator lights on another project.
They were great during the day, but distractingly bright during the night, so I made an auto dimmer circuit out of two transistors, two 24K resistors,and two other blocking diodes for the common ground path, so that when the headlights are turned on, it shunts the ground path through a 100 ohm resistor, dimming the LEDs at night.
You could also do something similar on the power in side of the LEDs, though it would take a small circuit for each LED, rather than one, on the ground side.

What bulb types are you running for the interior lights? They look really bright. The stock ones are #90 bulbs. Are yours LED's as well? If so what brand and number? Looks Awesome!

Did you wire in resistors as well or are these LEDs rated for 12VDC? I did another project that used LEDs:
Cub Scout Pinewood derby car (truck) -- entered in the "Dad" class, it was slow as molasses but looked cool.
I think your use of LEDs behind the dash is a fantastic idea! I love the green tint as well.
I burned up 3 LEDs (not cheap ones either) during the process because I wired them in parallel with a resistor and these were rated for a lower voltage than my 9v battery power supply. Doh.

T1076 Just pulled them to check they have been in since I bought the car haven't had any problems with them

In the shot of the '64 cluster, are the lights reostated up or down? Did you repaint the cluster interior? Dennis

I'm pretty sure that all the way up or close to it, only part that was painted was the black side of the piece that hold the glass the rest was left as is the original mint color was pretty washed out and flaking.

these are 12v just change them out like a regular bulb nothing else needed
