Question:

I am looking for replacement LED lights for my trailer. The clearance lights are 2.5 inch . On of those is marked DOT AP2 90 and PM 143. The stop, tail turn is marked DOT IPP2RST 16 and PM 421. I also need the grommets they are marked PM 421 18, and PM 143 18. Can you tell me the part numbers I need to order? Thank you!

Expert Reply:

Although the DOT numbers you gave me are codes for what testing was done on the lights, I do have a solution for you.

For your 2-1/2" round clearance light we have the Peterson Piranha LED Light # 162R with the wiring and grommet as part # 162-18K.

We have had people ask about your PM 421 light before and have found that the Optronics # STL22RB with the grommet # a70gb are perfect LED replacements. If you need new pigtail wiring for these you can use part # A45PB or the angled part # A47PB depending on how your wiring sits.
