What You're Actually Buying
This is a passenger-side, driver-quality LED projector headlight built to replace the factory sealed-beam or reflector unit on the 388/389 cab. Projector optics mean the beam pattern is cut sharper than the old halogen units - less glare for oncoming traffic, better spread down the shoulder at night.
The white halo ring around the projector doubles as your daytime running light. It's a common upgrade on Peterbilt trucks running night freight or fleets that want the DRL look without hacking wiring harnesses together.
Fits 388 and 389 model years directly - the housing shape and mounting tabs on the 367/567 are close enough that this same part gets ordered for those trucks too, but check your VIN or pull the old headlight and match the mounting bracket before you assume it's a straight swap.
Why These Numbers Cross
P54-6101-110, 16147, 37681, and 37671 all show up against PET-014B-R because Peterbilt used more than one part numbering system across model years and dealer catalogs - factory service number, parts book number, and aftermarket cross-ref numbers don't always match up clean.
What actually matters here is the housing dimensions, the mounting bolt pattern, and the connector plug on the back. LED headlights don't have the drum-size or spline-count issues you'd worry about on a brake part, but the wiring harness plug and halo ring wiring need to match your cab's connector - some Peterbilts ran a different pigtail depending on when the truck was built.
Surest way to confirm: pull the number off your old headlight housing (usually molded into the plastic near the connector) or run your truck's VIN. Don't just match a number in a catalog and assume it's good - a five-minute check saves you a return shipment on an $600 part.

PET-014B-R Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to PET-014B-R. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 16147 fit my Peterbilt 389?
Likely, but confirm with your VIN or the number stamped on your existing headlight housing first. Peterbilt reused housing shapes across several years, and the 389 had running changes mid-production - a quick VIN check on our end avoids a wrong part getting boxed up.
Is this the same as the P54-6101-110 headlight?
It cross-references to it, meaning the housing and mounting match, but 'same' isn't a word we use loose - different manufacturers can have slightly different connector pigtails or halo ring wiring. Pull your old part number and we'll confirm before you order.
Will this headlight work on my Peterbilt 567?
The 567 shares enough housing geometry with the 388/389 that this part gets cross-referenced there often, but it's not guaranteed on every build year. Safest bet - check the part number on your current headlight or give us your VIN and we'll verify before shipping.
