Recently purchased some led headlight bulbs for my 2020 ram 1500 classic (first time dealing with led bulbs), they did not come with any resistors and I was wondering if I needed any and if so what type?

Well the main reason you may want them is CAN buss systems are looking for a "voltage usage" on a circuit. If they do not see that you will get a message of a headlight being out. Some will also get a flicker in the bulbs. You can look them up on amazon. They should be a direct plug in type deal for your bulb.
