The bulbs behind my Tachometer burned out a while ago and I decided I would replace them with LEDs. I also replaced the ones behind the speedometer as well. Overall I probably spent more on this project than normal, but I bought a few miscellaneous items. My car is a 1992 Nissan Pick-up. NOTE: This may or may not work for you. But it doesn't hurt to look and see if you really want to do it. Tools: -Standard Phillips Screwdriver -Precision Screwdriver Set -Leatherman* -Vise Grip Pliers* -Multimeter -Soldering Iron -Solder -Alligator Clips *Optional Parts: -4 Ultra High Brightness White (Or color of your choice) LEDs. These can be swapped for almost anything really. The brighter the better though. -Resistors. Varies based on LEDs.
