    I'm sure the answer is YES, but I can't find anywhere to confirm that. So since the
    dimmer switch has come up for topic, when you replace the dash gauge bulbs with LED,
    does the dimmer switch still work with LED. I know some of you are thinking is this guy
    for real

    Be nice, I'm just asking and pretty sure the answer is yes. But not totally for sure...

    Dan, they get softer as the dimmer switch is engaged. However, I don't think the lights were made for dimming. I couldn't find any that were made to be dimmed, but then again I didn't look that hard. Here is the link for the ones I got:https://smile.amazon.com/Yoper-64111...ct_top?ie=UTF8

    I had the same problem. I re-glued them and then slid a machined collar over them. It is nice to access to a friends machine shop!

    Well I am done with the LED lights, but because of a broken stud on the gauge panel, it will take me a lot longer. I would say two hours should do it. Drop the steering wheel, remove the gauge panel, when you get that far, remember there are two bolts in the bottom that are hard to find unless you know where are. Then remove the gauge panel, check each gauge light for the number of LEDS you will need (usually 2 per gauge). If you have a clock, you will have to get a regular bulb, it's smaller than the BA9 holder. Once the LED are in place test them out, if they all work (they should), if not check the rheostat on the three switch module. Once everything is together put the gauge panel in place, put the steering wheel back and you are ready to go. Most people would be able to do this in less time, but I am old and slow.

    I need to make the swap of all the parts from one gauge panel to another. I’m guessing 12 hours.

    I found this to be quite useful especially for those like myself whom haven't had the pleasure of removing the dash
    Thank you Kyler for putting the 3 part series together

    Bob check out the below thread posted by Otto in 2005. Very informative on how to
    repair a broken dash gauge mounting stud

    Bob, it will take less time if you take pictures of the wire placement in each gauge. I took each gauge out and immediately took the wires and put them in for each gauge (one at a time). The all I have to do is put the gauge in the panel using the two mounting screws. The six switches are going to take some time unless I figure a way to take them out without removing all the wires. I will take me a while, and I will post any "shortcuts" that I figure out.

    Dan, to see how I hooked up an LED (pulse width modulation) dimmer for my dash gauges, see my post #11 here. I tested it to work well but it has yet to go in a car.

    Terry, good information. My GT has been modified, so much of the information can't be used. I have a 12 circuit blade fuse box and don't have the "plugs from the wiring on the gauge board to the fuse box. If you have a stock GT, the information is invaluable.

    Worked on the GT today, put a screw in like Otto said, now I don't have to tear apart the whole gauge panel to get it done. I have to put in the radio and the switches, and screw the gauge panel in place. Tomorrow I should be able to get some pictures of the LED lights both settings on the dimmer switch. One will be bright and on not so bright.

    Pictures

    OK I am going to post the pictures of my gauges with the blue LED lights in place. The pictures are time lapse an leave a little bit to be desired, but I think you will get the picture (pun). The shop was dark because all the lights made it impossible to show the blue light. So I shut off the lights. After taking a few pictures it became evident that I need the tripod to put the camera on. While these pictures are better, the still leave a lot to be desired.

    Terry, if you don't have anything else to do except change to LED's, It should be pretty easy. Just undo the gauge cluster and replace the lights for the gauges one at a time, put the led in and seat the led light. Before you put the gauge cluster back, make sure everything works to your satisfaction. Don't forget the dimmer switch at this point. Good luck.
