Default Cluster Color change problems

I am doing the interior color change using Trunkmonkey's tutorial. Everything has been smooth up until now. I am sanded clean and my needles still work, however I seem to be burning out LEDs like nobody's business. I put the LEDs into the twist lock bases, fire up the gauges and the LED's are burning out. I have got a couple to work but it has been like pulling teeth. I ordered 20 of:

out of the 20, looks like 18 have burned out. Are these just garbage bulbs or is something else wrong. Whats more, the bulbs that do work start out on, albeit dim, but they do start, and then as i adjust the brightness to be brighter, they grow dimmer. I have no clue what is going on, any and all advice will be greatly appreciated. Thanks.

Car is an 2004 2.5rs btw, my hvac and odometer both work properly with the dimmer.

Either junk bulbs or you've managed to mix up positive and negative.

^^ LED's obey polarity, and will only work when connected correctly. ie; positive to anode, negative to cathode.

Sounds like low-quality bulbs or incorrect resistance.

That said, I can't understand why the dim when you 'increase' the brightness. Are you sure you don't start with the dimmer switch 'bright' and they are just very dim?

Perhaps you might look into LED's with a higher MCD output, or re-calculating the resistance?
