Rear Breather Light Panels – Peterbilt 379 & 389 | 1.25″

Rear Breather Light Panels – Peterbilt 379 & 389 | 1.25″

Product Description

Don’t let your rear breathers go dark — complete your build with Alpha Series rear breather light panels, built tough and polished to shine. These rear panels are made from the same ultra-durable 12-gauge 304 stainless steel as our front kits, with a flawless #8 mirror finish that matches your OEM or aftermarket breathers perfectly.

Designed to fit all Peterbilt 379 and 389 models with 13″ or 15″ Donaldson or Vortox air cleaners, these panels are a direct bolt-on upgrade. They use the existing breather strap bolts, so installation is clean and simple — no drilling, no fabrication, just a perfect fit that works right out of the box.

Each panel is laser-cut to accept six 1.25″ round LED marker lights, giving you that glowing rear watermelon light effect that turns heads at night and boosts your visibility on the road.

These panels are fully compatible with:

• United Pacific 36036 (Red lens)

• United Pacific 36037 (Red/Clear lens)

• As well as any aftermarket 1.25″ round LED markers that fit a 1-3/8″ grommet hole — giving you total freedom in your light setup

These aren’t cookie-cutter panels. The Alpha Series rear light panels are a unique offering in the aftermarket world, bringing a new size of breather light to rigs still running traditional 3/4″ or 2″ setups. This mid-size 1.25″ layout gives you that modern Peterbilt 589 look while keeping the classic Peterbilt profile.
