In case anyone is wondering about swapping out the old 168 or 194 dash lights for LED's, let me tell you this - DO IT!!! I have had my truck for 1.5 years and have never seen the dash at night. I pulled out the original 194 bulbs and replaced them with 168's and cleaned the circuit board terminals, no difference. I decided to give Superbright LED's a try. Purchased (4) of the 360 degree bulbs (5 LEDs per bulbs) for the (4) main lights in the cluster and the results were amazing!!! Without a doubt the best $20 ever spent on my truck.
