Hi everybody.

I am currently changing my dash lights to led dash lights all the led's are working but when I put them in the dash and go to turn it on they don't work has this happened to anyone else before or can anyone help?

Any help will be much appriciated.
Thanks

99% likely to be the polarity. The LEDs simply won't light up if you've got positive and negative the wrong way around. The best way to get them right is just via trial and error since the little LEDs aren't often marked.

You can just pull the LED and the holder out of where you plugged it in, turn it around 180 degrees and put it back in. You don't need to remove the LEDs from the holder since you can just turn the whole thing around. Sometimes takes a few times to get them all correct so test it without putting it all back together to see where you're at after you turn them around.

Good luck
