If anyone is wondering what the polarity of the Auto Climate Control bulbs are, and this is important if you are replacing incandescent to LED here it is:

+ + - + -

O O O O O

- - + - +

This uses T-5 LED bulbs from Superbrightleds.com. You can get the LED's from eBay or Amazon too. The ideal size is T4.5 but a T-5 will work. You may have to trim a bit of the board off with a file or dremell tool. Our old boards are a bit thicker than the new boards so it also may be a bit hard to turn them to lock them in place and filing of the little tabs on the bulb may make it easier. Remember POLARITY makes a difference with LED's they must be put in properly for them to work. Other than that you need not do anything else.
