I think they're just plug and play without any resistors. Try one at a time and see if there's a problem. If not replace the rest with LED
Only turn signals need the resistor.So I just got those truck a little bit ago. Went to Costco and got rear ended in the lot. Since I want to change the assemblys anyway it wasn't a big deal. I KNOW NOTHING about electrical on cars. I'm wondering if I buy LEDs all the way around, do I need to put in a resistor? Or is it just plug and play? Reason for the chang is I want a dark look to match the tint.
