LED Stop/Turn/Tail Light, Details & Fitment

Red 4in round LED stop/turn/tail light for trucks and trailers. Direct replacement for any standard 4in round S/T/T lamp: drop it into the existing grommet and plug into the standard PL-3 pigtail, no rewiring. The usual reasons to swap: burned-out or dim incandescent lamp, cracked lens, water intrusion, or upgrading a trailer to LED so you stop replacing bulbs. Sealed epoxy-encapsulated electronics shrug off moisture, road salt and vibration.

Install notes

Reuses your existing 4in grommet and PL-3 plug. When replacing incandescent lamps on the turn circuit, make sure the flasher is LED-compatible (low current draw can cause fast-flash with old thermal flashers). Incandescent version of this lamp: 571.LG40R.
