Read all the 'How To' on changing out those ugle yellow lights in the dash panel. Not having much success in getting the lights to work. The first one didn't work. Tried number two. It lite the first time I tried it then after changing out another light, it stopped working. The next two won't work at all. Any ideas? I thought maybe electrostatic problems but tried one without touching it at all and still nothing. Does anyone have any experience with this?

Make sure the polarity is correct. LED's are polarity sensitive.

What?! That could be it. It said in the How to, that it didn't matter but that would make sense.

OK, that must be the problem. So how can I tell which way they go? I didn't see anything that looked different from each contact side on the board or the light itself. Does it hurt the lights to touch them? There is something on the package that mentioned electrostatic issues.

Where did you order the LED's from? There should be a schematic that shows the polarity.

Mouser electronics. No schematic just the lights came. I re-read the how to post and it does mention that the polarity needs to be correct so I'm sure that is my problem. I just need to figure out how to tell which way they go. Any suggestions!

If you look closely at the internal construction you can see there's a difference in the two sides. I just arranged mine like for like and didn't have any problems. In this post there's a closeup picture of one of the original LEDs that shows there's a yellow line on one side which indicates the cathode side.
Hopefully you haven't already removed all of the yellow LEDs and can still do them one at a time after examining each orientation. If not you could use trial and error by plugging the unit in after installing each one to test it.

Beek, thanks. I did notice the yellow and blue strips under the lights. I didn't take all the yellow lights out yet. I'll check each one as I do them.

What are the specs on the LED's you are using? Do you have the part # and manufacturer name? I am interested in doing this myself.

Never mind, I found the "how-to" document, I am all set now.
