What this mod does
Project 3XX LEDs+ bundles into a standalone mod all the lights that came with Project 3XX, the well-known ’90s Peterbilt by guidot and the Half Fast Gaming (HFG) group. It’s one of the author’s most downloaded add-ons, with more than 10,000 downloads on TruckyMods.
Light styles
- Lights for the air cleaners.
- «Chicken» lights, the classic style seen on American trucks.
- Side lights.
- Mini LEDs.
- Sequential ovals and regular ovals.
- Round combination tail lights (marker, turn signal and brake), added in version 1.44a.
The parts and flares are from SCS; guidot handled bringing them into the game. Version 1.02 added support for the 9900i parts pack.
Version and compatibility
Version 1.45a, from September 2022, is marked by the author on TruckyMods as compatible from 1.45 to 1.61; the page was updated on September 20, 2026. It doesn’t list any DLC or dependencies.
Author’s warning
Some of the lights are very demanding on modest hardware. Keep that in mind if you play on a low-spec PC. The page doesn’t say which trucks support each light.
