You'll need 6 lights for the cluster, 2 for the HVAC controls. The headlight switch uses a smaller version of the 194 and I'm not sure what size is that (74 maybe?). Cheapest place I've seen LED's are http://www.superbrightleds.com . There have been some people that have said that the blue LED's are a little too dark for their tastes, but I wouldn't know about that - I ended up using some white HID 194 (regular bulbs, but they run much hotter - I would recommend against getting them.) bulbs due to time constraints when I was putting in my SHO cluster. These are really bright, but like I said before, they run really hot - I ended up melting the sockets in the 2 HVAC lights; I'm running them at about 3/4 power through the dimmer right now.
