I today I set out to swap a few more of my stock bulbs in my gauge cluster to LED's, today's project being my high beam indicator and turn signal indicators. There is no problem with the high beam indicator after the swap, but the turn signal indicators are no longer working. Does anybody have any insight into this? If I put stock bulbs back in they work fine, so I'm thinking that it had to do with the resistance of the LEDs, but they are supposed to have built in resistors for this. Has any body had this problem, and does anybody know the fix?. Also, a little off topic, but the warning light in the center of the cluster never comes on in my car, should it at least at light at startup or something?
If you have an overhead check panel, the brake warning should be lit on it, unless you press the brakes will starting her up.
CHECK should be flashing on the dash then.
I'm pretty sure I'm not going to like the LED stuff. Curious anyway, so post a vid if you get it to work..
Alright, I got the LED's to work and figured out what my problem was (wrong polarity on both bulbs..), while also managing to break one of the black bulb retainers in the process, so I'll be sending out for one of those soon too. I'd be more than willing to do a write up of a full LED gauge cluster conversion, and I think you'd be surprised. The reason I'm doing this, is because in 1984 when the car was built, they had to use filters to get the light to show the color they wanted, so the high beam indicator had a blue filter, the problem (for me at least) is that the white shows through the filter, so you end up with a very washed out blue, and the signal indicators look almost lime or yellow even. With the LED conversion, the high beam indicator is a very true blue, and my blinkers are a very true green. The only hesitation I have with sharing my cluster right now is that the right side of my cluster is dead (apparently a pretty common problem) and I believe that the problem is a broken solder or something, although I'm going to re-look over it either tomorrow or sunday and try to pin-point my problem and hopefully fix it. Other than that though, I'm very in love with my interior, and the only bulbs left to replace with LEDs are the HVAC panel bulbs. I'll try to remember to take pictures tonight though to post.

Its worth noting that they aren't that bright in person, I'll try to take some better pictures later.

Again, I'll do a comprehensive DIY with part numbers and pictures once I get the right side of my dash fixed (I need to solder on a jump wire) and post it, it really is a great mod, and with the parts I used the LED back lights are still dim-able throughout the car. It's subtle, but it really adds to making the cars technology feel less out dated. I'm also doing full exterior LEDs, but I want to finish up my interior first. The reasons I did it are: longevity/reliability, performance (like you said, on-off, not dim on dim off like the old ones, and brightness), and customization (I'll include in the DIY how to remove the orange filters so you can get a truer red or change to blue or whatever color you want).
