(5) 74-xHP3 bulbs for the speedo and (2) WLED-x5 bulbs for the temp controls. Heres a thread that may help. scroll down to the 5th post and you will see how to do the temp controls. for the speedo, i used a mach 1 speedo because the colored film on those is white so i wouldnt have to remove the green stuff to get the color i wanted. good luck! let me know if you need anything else

hey what bulbs did you use for the speedo, and how many? also the temp controls how many did you have to buy and what kind for those lol. I like the way it looks way better than reverse glow guages. what all did you have to do to make them work well
