I went through all 16 pages in the exterior section and also did a search for led's but did not find what I needed. Has anyone replaced the rear lights (stop/brake/reverse/turn/license plate) with led's and if so, which did you use and did you have to use a resistor with the turns?

LED's for the rear
- Thread starter stepbill

Look in the owner's manual. It gives the bulb number and you can cross reference to aftermarket LEDs. The back up and turn can be changed,. the third bulb which is the bottom one is a dealer serviced item. THe owner's manual lists a 7440 and a 7444. However the bulbs that came out are a 7440 and a 7443. The 7440 has a cross to a 7440 LED. Found a 7443 LED at Advance Auto. Kinda strange, but that's what was in the truck.

2022 Tradesman rear bulbs are listed WRONG in manual -
- For Brake/Tail the owner's manual listed 3157K BUT bulb was physically a 7443 bulb (3157s don't fit/secure so waiting on exchange).
-For back-up lamp manual listed W21 and it was. I replaced with a 7440 LED
-For Turn lamp the manual listed PWY24W BUT the bulb that came out was a WY21W and I replaced it with an amber 7440 LED.
