White LEDs from Oznium.com For my climate control I used this LED module with white LEDs in it (the long black skinny one)... (http://www.oznium.com/led-modules) ...only because I had previously cut the bulb sockets off for other bulbs. Had the bulb sockets still been there I would have just used the same bulbs as I used in the cluster, which is what I recommend doing. Once again I recommend the T1.5-xHP bulbs due to them having a wider beam than their cheaper counterparts. (http://superbrightleds.com/cgi-bin/store/commerce.cgi?product=CAR&next=50#T1.5-xHP) What you'll do with these is just pull them out of the socket they come with, and push them into the socket already on the climate control. It's a direct swap. There are 2 bulbs in the climate control. All of the LED bulbs are polarized, so if they don't light up, just flip them around to reverse the polarity.
