I have been asked a couple times what size resistors to use when converting to LED signals or other after market signals, so i created a spread sheet to calculate it for you, all you need to do is measure the resistance of your oem signals and your new signals and punch it in, it then tells you what size resistance you need and what wattage it should be. let me know if you have issues opening it or if the calculation is wrong, keep in mind that the resistance value it calculates is the maximum it can be and the wattage calculation is the minimum.
